Well, I just spent 5 minutes switching through the various app icons on the webos menu - (hovering over an app displays a flat colour associated with that app across the entire screen apart from an icon in the middle and the icon tray at the bottom - should do the trick no?) and I can honestly say that I cannot see any uniformity issues.
Maybe I'm just lucky but my understanding is that it's not a hit or miss thing but an issue inert to every oled TV so I dunno...
Until I do see signs of burn in, my stance is that I own a TV that is significantly better than any of those you listed on a previous post & even if it were to show signs in say, a year or two, at which point does it get bad enough to completely offset the advantage it has in image quality?
If I had the choice between a non-oled or an oled with a bit of burn-in in the top left of the screen where the BBC logo lives, I'd still choose the oled...
Again, this is just me, I'm sure that view would split opinion but I think the presumption that burn-in of any kind nullifies any and all of the other advantages the oled holds over it's counterparts is not fair.
And I have zero loyalty to oled itself - if like you say, next gen qled trumps it then qled will be my next TV.
I appreciate the more constructive tone to your recent posts as opposed to the ones where you were telling me, as an oled owner, that I feel bitter - as that's what got my hackles up!
Where does that belief come from though? Just from the ultra black?
Compare the specs:
X900E Small imperfections can be noticed in the dark green and blue, but these are almost negligible.
C7 Small imperfections can be noticed in the darker shades of color and the dark part of the greyscale. Note that when the TV is set to 'PC' mode, via the input menu, the banding is much more visible, and this for all picture modes.
White Balance / color deviation (smaller is better)
X900E 2.15 / 2.37 pre, 0.25 / 1.97 post calibration
C7 4.47 / 3.04 pre, 0.15 / 1.22 post calibration
Color Gamut % DCI P3 xy/uv
X900E 89.57% / 96.07
C7 95.99 / 97.53
Color volume % DCI P3 normalized/10k nits (important for HDR, how well the colors hold up over the brightness range)
X900E 80.4 / 46.5
C7 81.1 / 44.4
Both are still quite low on the rec.2020 color scale, it will be a while until GT Sport can show it's true colors.
The C7 also has ABL, dimming very bright scenes to protect the tv I guess. Check the HDR measurements on rtings.com, too many too list, yet they say that ABL is a negative for HDR gaming, and from the figures, depending on how much of the screen is bright, the C7 varies from 718 nits all the way down to 137 nits max, a factor 5 difference. X900E is very stable in light output.
HDR ABL, good value < 0.07
This is comparing a high end tv to a mid range tv. So what is significantly better?
Ofcourse all these minor differences don't really matter when watching normal content. Neither does perfect black, unless you watch in a completely dark room with dark walls wearing dark clothes. Otherwise the only times you notice it when there is a logo on a further perfectly black screen. ABL is probably also not all that noticeable with normal content but it's a trade off, perfect black vs stable whites.
Perhaps I need to see it in somebody's home, well calibrated and all. In my local home theater store, set up in a low ambient light viewing room, playing a normal movie, I don't see the significantly better picture. Plus that store told me they were phasing out LG because they've had a lot of problems with them and are now going to stock Sony instead.
