Well, I think the KS9000 and KS8000 are both excellent sets for dark scenes, considering the fact that they are edge-lit. I watch movies in a room with absolutely no external light, and a non-defective KS-series will do about 90% of what I want it to. But, it's that last 10%, those dark scenes where a single object is illuminated, where it didn't do so well. The night scenes of Beach Buggy Boys part I and II of The Grand Tour does a good job of highlighting, pardon the pun, these flaws.
That being said, with the lights on and when the room is illuminated by sunlight, I found it impossible to see these same defects. And I looked for them. The blacks are very deep, too. A great example of this is the loading screen on Skyrim, which has some bright object or figure on an otherwise pitch-black background, and that background is eerily-black. It looks fantastic.
Basically, the things that I notice (or people on here who are also particular about dark scenes) are so minute that most people won't notice. I'd probably have to pause a scene and point it out. If you're in a relatively bright room, or use bias lighting, these same defects are going to be very difficult to see.
It's a tough choice for me. I owned both a KS8000 and P series at the same time, and found the KS8000 unbearable. I was booting up ESO on my PS4Pro with HDR, and when it came time to adjust the game's brightness on boot-up, a huge vertical column of blooming took up the middle of the screen. It was so bad that I could barely calibrate the game brightness with it there. I appreciate your thoughts about how rare those times might come across, but it does mentally bug me knowing that fault is there. There is a large window in my small room that constantly shines glare on my TV, so I figure the KS8000 would trump the P's picture most of the time I'm able to play, though. I'm just at a lose. I ended up returning both as they both were too small, however I'm back on the market for a 65-inch from Costco, but I still can't make up my mind.
From what I've learned, this is how I rationalize the pros and cons of either:
Vizio P - has no faults (blooming, bleeds) in screen from design or materials; has great blacks, but doesn't get as bright as a KS8000; slower boot up times and a less-than-desirable UI; more prone to reflections thus negating some of the benefits of a good picture during the day.
KS8000 - has severe blooming and bleeding in dark environments on black backgrounds with bright images in foreground; higher spot brightness (instances of light such as explosions, sunrays, etc.); less prone to reflections; appealing UI and fast boot-up time.
With writing out the pros and cons like that, it feels like the KS8000 has more noticeable faults
, but less noticeable benefits. Still, I'm at a loss at which ones was better. I might just take a step down from the $1500-1600 range of these two displays and get something cheap for the time being; I hate spending a lot of money but feeling like I'm making a compromise.
