So things look interesting in the big screen (75"+) top end TV market. You have the Samsung Q90 82" at $6500 and the Q900 75" and the LG C9 both at $7k (all MSRP). The Q80 82" is perhaps a wildcard, but we don't know its MSRP and there's been virtually no early reviews or impressions of it that I've seen. Anyway, I highly doubt that it can even come close in PQ among these 3, but since it'll probably be $1k or so cheaper, I'd love to be wrong about that. The 82" Q900 at $10k, I don't consider to be price competitive to these because of the relative cost per inch and the fact that it will depreciate much faster than the others (in case you want to sell it in 12-24 months). I'm in the market for one of these TVs to replace my 65" Sony A1E because I want something bigger. The question will be just how much lower quality the Q90 is relative to the Q900 and C9. The Q90 screen is about ~20% bigger and the price is ~7% less. If it's close enough (obviously relative per person and usage), that's the one I'll get.
The problem for me of going from OLED to LCD is that I immediately notice blooming, poor blacks, and poor viewing angles. But, the sheer size and immersion is a huge advantage with large LCDs. That's why I'm hoping the 82" Q90 is close enough. I'd consider the Q900 over the C9 because it might be more future proof at 8K and using the upscaling for games and other content. But I'm biased towards the look of OLED and I assume that the C9 will best the Q900 by a decent enough margin to make me pick it in a choice between the two, until and unless reviews prove me wrong about that. As far as brightness is concerned, I work during the day and so most of my TV viewing is at night. OLED is bright enough for the times I do watch during the day and obviously (thus far) bests everything else at night, which is why I have one. I don't game on it much, but if I wasn't concerned about BI, which I wouldn't be if I had LCD, I probably would game on my TV more.
The other option is the discounted pricing of the 77" C8 and even the 77" A1E. I won't mention pricing, since it's not allowed here, but we all know that they're discounted by thousands. If these new TVs aren't substantially better than the 2018s, and they might not be, then I might go that route.
