I'm talking about results, not promises. And Vincent has little credibility especially when it comes to TCL considering they fly him around. In fact, his coverage was absolutely pathetic for the 8-series and only once everyone showed how bad the TV really was did he start talking about how awful it really was. I have very little trust in him but he still has some useful info from time to time.
It's both. There's a lot of caveats to burn-in based on usage & settings. If we look at the RTINGS tests, the CNN TVs show burn it on magenta showing clearly at 20 weeks (for max brightness) or 30 weeks (200 nits brightness). Now obviously if you don't watch the same thing over & over, the rate at which you hit the pixels in the same way will vary wildly based on content, so the 20 weeks (or 2800 hours) is the worst case scenario. If we look at the other footage, you can see they all pretty much give up around 100 weeks, with the exception of COD WW2 which is the least stressful test you'd ever do, so you that's at 14000 hours or so. So let's say that you can expect to be mostly burn-in free for between 3000 and 14000 hours.
Now the reason I say it's going to burn-in before the useful life of the product is because, think about it, will the OLED PQ suddenly be so bad it's unusable or you wouldn't want to watch it 5-10 years from now? Ofc not, just look at CRT & Plasma still kicking ass today. 14000 hours at 8hrs a day is less than 5 years. And since it would still have great PQ even if you were to upgrade then, you could still have used it in another room or given it away to a friend/relative to use, but with burn-in pretty much guaranteed by that point, you can't.
So that's why I say think about OLEDs in a much more disposable luxury kinda way.
