My TV was delivered last Thursday (2 days late, but anyway). I have it all set up and I'm really happy with the panel. Pretty much no DSE whatsoever. I'm also really pleased with the performance of the TV and I don't have any issues with the perceived blooing. Sure, it's there if you look hard enough, but in most cases the heaps of extra brightness really shows with HDR content especially. I'm coming from a 65 inch LG OLED.
The only issue I have is that there is a very tiny crack at the very right ridge of the screen which is the size of a pencil tip roughly. It's right on the edge of the panel and of course, you can't see it unless you're right up at the set.
I spoke to Samsung about it and said that I would be happy to keep it, however if it developed into a crack then I would like the set replaced. They told me if it happens outside 21 days then it would be a warranty claim, therefore, not covered at all. So at the moment I've opted for a replacement. Now I'm concerned I might get a dud set and I'm in two minds whether to just keep it. It seems like it would be very unlikely to develtop into a crack but regardless, I'm not sure if it's worth the risk.
The other thing I was disappointed about is that the back of the set was covered in fingerprints and was a bit dirty however, the actual screen was perfect (other than the tiny crack) and still had the protective film on it. I'm guessing it just wasn't handled very well when it was being boxed up. It also came in a QN90 box for whatever reason, but it did have a few QN94A stickers stuck on it. I've seen a few people mention this before.
