I use a PS4 pro on a KS8000. The TV is very good for that as well as movies and TV. I watch in dark room and I went through a Sony X900E and a B6 OLED also and wound up keeping the KS8000.
The Sony is a lightly better in dark room performance although with its small zones, it actually would light up black bars even more than the KS8000 if the brighter object in the film was near the upper or lower bar but generally it was a little better but you would probably not tell difference without going straight from one to the other.
The OLED was better in dark room but I actually like HDR content on the KS8000 better (brightness makes a difference.)
I rarely notice the edge lit deficiency, compared to direct lit, in actually content - yes there is blooming on movie credits etc., but no real frequent problems in actual content. In HDR I can tell that the black bars are less uniform, "IF" I look for it, but if I am engaged in a movie, I do not not notice it. Note: for black bar movies, I use a bias light behind the TV or sometimes use a small light in the room. Note: the X900E Sony and LG Oled both looked better with bias lighting also.
If you could get the Sony X900E for close to the same price, that would be a good choice because generally, in dark room environment, it was slightly better than the KS8000, but if $250+ more, I would go with the KS8000, especially considering the KS8000 will get HDR10+ and I do not think Sony has plans for the X900E.
