the green in the screen looks like light-green, washed-out, something you only see in defect display,
especially when youre coming from a samsung phone,
especially the first time you open your phone and see the color in the apps youre used to in other phones,,
I couldnt help but noticed the same thing and tried to do some tests to see if it's a common problem for Xperia Z ultra, or is it just some of us happend to have the same kind of defect display
of all the tests, here are the most comvincing ones:
first,
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
left is the one i took on desktop , right one is the screenshot on phone while playing the same youtube video in youtube app,
clealy the one on phone is more "light-green",
this is the proof that the "light-green" is intended by Sony rather than due to defect in the display, otherwise we would see a darker green like the one on desktop, (cause the screenshots took in-phone are what the hardware drew, rather than what we see from outside/what the screen displayed)
the second one
is a screenshot took in-phone, while displaying a .png pic file, on the left,, compared to what it's like when the same .png file was viewed on my Windows7, on the right.
No difference was found.
I quickly tried another pic that wasnt initially on the phone, prepared by sony,,,
here's the results:
: No difference to be found,
(when comparing i put the 2 pic file in the same folder and used a viewing software to quickly go back and forth between the 2 pics during which the same place of the 2pic was kept at the same place, zoomed by the same level,,,, and found no difference)
then, I copied the official demo video(Xperia HD Landscapes.MP4) to my desktop, screencaptured a frame to compare to the same one played on phone,
here's the result:
the one on the right is what the video looks like when played on my desktop,,,the result doent need anymore of my words.
So the conclusion:
While initially you may find the color , especially in google apps(casue they are the apps with obvious color youre most familiar with), washed-out,
the screen is not defect and can show the color green 100% fine,
it's most likely due to some Sony's weird software tweak,
which happened to all the video the phone plays, where the green is really "light" and feels unpleasantly "washed-out".
I can only hope Sony fix this problem as fast as possible, cause compared to Samsung 's famous oversaturating tweak(actually more due to the "side-effect" of being able to display a wider color gamut), which made almost everything on their phone looked absolutely more stunning and awesome,, Sony's tweak can only be concluded as, considering their long history in the industry and all the hype/triluminous/bravio engine/blahblahblah said in their ads,,,,, the most embarassingly retarded fail I've ever seen by such a giant multinational corporation.
any ideas?
I went from Samsung Galaxy S3 etc to the Sony Xperia Z and Sony Xperia tablet 10.1. There is a difference between the two screens. The screen colours on the tablet are simply stunning and to my taste.
I have just made a return to Samsung and bought the Note 3 and can safely say that I prefer the picture reproduction on the Sony. Different screen technologies produce different colours, light, contrast and definition. To me I see this simply as taste and not a 'fault' in either device.
I prefer the colour pallet of my Xperia tabet 10.1 to the new Note 3. I think we have to understand its a preference. I don't arrive at the same conclusions you do. I prefer what you appear to dislike.
Regards.

It's fine if it's only a tweak in the video playing,, if the green has to be lighter in a coloful video wiht all the other colors to contribute to a better viewing experience,
but the green and red in many apps in the phone are also washed out(doesnt in any way can possibly contribute to any thing except making you feel like looking at a 10 years old LCD with washed out colors)
I admit it really scared me at first, which may be the reason i did all these tests in the first place,,
I believe you cant compare with screenshot, as its just copying digital values of the screen. You will have to capture side by side with a good slr camera (live output) to compare results. I did a bit side by side comparison on some videos in a shop when i wanted to buy. But put off my purchase until i am sure.

Please add some words because I can't really see much difference there?

since screenshot showed us the difference we felt when looking at the display,,,it at least now represents the problem at hand,,
if it doenst, then the problem might be beyond screenshot(exp, quality of the glass above the LCD,etc), then we can use a camera to shoot the difference

Yes, if your assumption that the colors are so because of sony preprocessing. I believe screenshot will only show the effect of display preprocessing by the hardware/software but it won't show the end result of the inherent properties (color gamut/ depth, warmth/white balance) of the screen itself. Correct me if I'm wrong. And I would be interested in an SLR shot.

Exactly, screenshots do not give you the screen colors. The difference you see is only due to the JPEG compression. Do a color comparison with JPEG is also not accurate as well, different devices will show you different results even on the same screen. Only specific camera can really do it, can't be done with any commercial camera or camcorder as well. As the refresh rate and backlight are different between screen and screen orientation as well (portrait and landscape).

I never said it's accurate, and as i said above it wont address the problems that could occur to affect the colors after hardware rendering,
it' like,, if youre asking your doctor what the reddness in your palm mean, what kinda of illness could it suggest, by sending him a pic file of your palm (in jpeg form might i add),,,, yeah it's not accurate nor is it real,,but it at least does the job, if your doctor says he needs further investigation then you can consider sending him a "specifi camera" taken over-100MB-in-size TIFF file of your palm for accuracy.
since the jpeg file i used here already showed very obviously the difference we felt when looking at the screen,, what's the point of using another more accurate file format?

i was wondering about the same thing while doing the comparison,,
for example,, in one part of a pic it asked for the color of RGB(0,255,0), the screen tried to display RGB(0,255,0) but it looked different in our eyes than the RGB(0,255,0) displayed elsewhere, say my windows7 desktop(LCD display also),
Now i screencap the display, that place in the screencap file should be recorded as RGB(0,255,0) too,
so when i view the file on my desktop windows7, if it looked "normal" then it should be a problem of the phone display , if it looked like what we felt on the phone, then the display shouldnt be defective. (becasue that proves that it only looked different casue sony tweaked it so that it displays RGB(0,200,0) for the color RGB(0,255,0) in that specifi frame to look more appealing to the eye, not that it wasnt able to show a deeper RGB(0,255,0) color)
Now you may have doubt that when i screencapture on the phone, will the pic file record that place as RGB(0,255,0)? what if it was recorded ,say a lighter green, RGB(0,200,0) becasue it's what it's lilke and the screen wasnt able to display the color other normal screen displayed as RGB(0,255,0).
well, if that's the case then the same pic file showing the same green should look different on phone and desktop, which is certainly not true as my comparison 2 and 3 showed.
So, that screencap did work, at least in that comparison.
and now fianlly ,,
I do agree that we should use a camera to shoot together of a desktop LCD and the phone displaying the same pic file (AMOLED would obviously display a "greener" green for RGB(0,255,0) becasue of its wider color gamut), and then compare the green in that shoot, to cover any other issues , especially ones that could happen after the hardware rendering.
You are just comparing Sony firmware compression of an image display on the screen. It is not even about accuracy. Plug your phone by HDMI to a TV and make a screen shot, do you think the rendering will show how the TV displayed your picture?
Test on the phone itself.
Here original picture
https://dl.dropboxusercontent.com/u/66462768/MG_0133.jpg
Here the screenshot of the same picture on my XZU
https://dl.dropboxusercontent.com/u/66462768/Screenshot_2013-10-07-14-26-12.png
How come thank the screenshot show more saturated colors than the original picture on my XZU?
As one test is not enough now have the screenshot of a Asus transformer prime
https://dl.dropboxusercontent.com/u/66462768/Screenshot_2013-10-07-14-23-14.jpg
The IPS+ on my tf201 show pictures lighter with more saturated colors than my XZU, but the screenshot give the opposite. Asus compression is different and Sony compression give even more saturated colors that the original picture.
Edit: uploaded to dropbox for avoid compression on XDA. Sorry for the size ^^

what is your point exactly?
of course they would look different,
different device has its different tweak of displaying colors,
in case you still dont see my point: some company , for exampl LG, tweak their saturation to look like the samsung or to look better(for example, if a pic ask for 25% green, the display is tweaked to show 50% deep green), a screenshot of course will show differently, unless it's the defective display that oversaturated or undersaturated the pic,,,which when screencaptured and showed at the same time in another display should look all the same.(explained in detail in my last post).

My point is simply to say you spend a lot of time to make comparison, but to compare nothing. A screenshot is an image taken from data directly stocked on the RAM before any image processing, and so before the XZU make any modifications (X Reality) for improve image on the screen. So you only compared image decoding and encoding and not image on the screen.

then why you see the difference of the same pic file across devices?

Try to encode a CD with Windows Media Player and Itune, both to MP3 at 320 kb/s, then use it on a sound system (if it is on poor quality you may not hear it), you'll hear that the sound is different. I am really sensible to sound and can clearly feel the difference. Same go for JPEG or PNG or any image compression, each manufacturer use his own build in encoding program and process. Even if the extension is the same at the end, the rendering will be different.

well except that we all already see other big differences like,, listening to 2 different songs,
so without your fancy ear capibilities we already can tell that it's different , and no matter how the comression or even bitrate is processed, 2 different songs do sound as 2 different songs

as my first replay already said, which is the point ive been making this whole conversation
if the difference is subtle, it may be casued by other issuses, like the compression you said, and if we can barely see the difference, more accurate camera shot and file format should be used to compare
but here, we already see the very different color density like we felt when saw with naked eyes
like if you hear song A sung by devices A as " oh l love you so much"
and you record it , compare it to the same song sung by devices B as " oh I like you so much"
and record it ,,and when you compare them , you dont even need to consider what compression or bitrate you used to record, casue no matter what, you can already clearly see the difference
and then you start to wonder if it's devices A 's maker tweaking, that made it to sing "love" instead of "like" to make it more appealing , or is it that it was defective and wasnt able to produce the sound "like", and so you start to do the comparison 2, and 3 i did.
got it?
