One anecdote for another - I have an LG CX which released in 2020. It's on basically 24/7 (rotating photos through a Chromecast when not actively in use), occasionally I'll turn it off at night. It does regular pixel cleaning on its own that sleeps the panel for a few minutes.

I've not seen any burn-in.

All of these burnout 'tests' I've seen (this one, and RTings as well) purposefully use static content and are basically abusing the panel in a way that is specifically advised against. I find them pretty useless for anything not an office TV on the wall running CNN 24/7, which I will never be doing myself.

I don't think anyone familiar with the tech will deny using these panels in such a way will cause burn-in, even the test here:

I think it's pretty avoidable on a TV, the real issue comes from what you need out of a desktop monitor. I have a Dell/Alienware (Samsung QD-OLED Panel) that's about a year old without any visible issues, but it's still early to tell in that case.

The tech has gotten better, but the problem still very much exists.
