OLED's degrade over time. Different colors become less glow-y as a screen ages and even as certain colors are used more than others in different sections of the screen. There's also OLED burn-in where an image can semi-permanently or permanently burn into the screen based on displaying the same image over long periods of time. I recall hearing that blues are more susceptible to degrading than other colors...

How much any of this happens depends on the quality of the screen. Cheap OLED screens can suffer burn-in extremely quickly, while the highest end ones are much more resilient. But again... yep... thermodynamics.

You're not wrong. One reason I bought an OLED anyway is that I watch very little broadcast or cable TV (which often have logos or chryons always present). I was worried about game HUDs, but I've had very few problems with image retention (and no burn-in--they are two different things) with my screen (I do take precautions). I did have image retention once when I fell asleep with a web page up, and for some reason my Xbox didn't automatically dim like it usually does. My TV has a pixel refresh feature that took care of that problem. My TV is/was one of the best according to the reviewers, but I don't know how much difference there is in the quality of the actual pixels across brands. I think I read that LG manufactures most screens no matter the nameplate. It's the other technology between price points and brands that differs--at least that was my understanding a year ago.

P.S. I suspect microLED is the next big thing that will have the advantages of OLED without some of the downsides.
