OLED TVs have an unshakeable association with burn-in. Admittedly, this was a problem with some of the first-generation models released back in the mid-2010s. But these days, burn-in isn't at high-risk to happen unless you do something really dumb with your OLED TV.
What constitutes doing something dumb in this scenario? How about watching the same channel without changing it for thousands of hours in a row over the course of 441 days.
