My experience with my SONY 55A8 with aprox. 150 hours of use.
I dislike the way ANDROID TV works in comparison with the WEBOS from LG.
WEBOS is much more user friendly than the Android TV, but the capabilities of Android TV are much more deversified then Webos.
It takes a while to get used to the unfriendliness of the ANDROID TV system but is well worth to get proficient with, because of the all possibilities it has.
Regarding the 55A8 it took till about 125 hours for it all of a sudden become MUCH brighter then it was when brand new, note that it became a lot sharper at about 50 hours of use, but the biggest change came at 125 or so hours, almost became a 3D picture, things/people, seem to seperate from the background more, really neat.
After 5 years of having lots of problems with the LG oleds and multiple exchanges, I did have the last one (E8) that worked as intended, I think the picture quality of the Sony 55A8 is superior to the LGs at least in comparison with the last LG E8 I had.
To those of you with an Sony A8(H) with less then 200 hours, hang in there till at least 200 hours of use before you decide to exchange, because the best is yet to come.
My Euro 55A8 got its BIG improvement around 135 hours and the biggest noticeable change was the BRIGHTNESS and picture DEPTH, Brightness went from MAX(50) to having to set it back to 18, and that is a BIG difference.
There is a new software version out this morning OTA version number 6.5016.0631EUA
that is another thing I like about the SONY is that the explenation of what was changed in the firmware, is shown on screen when you go to update.
One thing I dislike is trying to find the user manual that explains the workings of ANDROID TV. It is hidden very well on the SONY site. It took me 5 times looking for it before I found it you can download it and then either print it or save it as PDF file. I chose to save as PDF because of its length, 164 pages.
