re: Large Format LG OLED vs Premium LED’s?

I'm roughly 2 years in on a 65 (I think b7). The screensaver, as stated, kicks in quickly, but I do have a Marantz receiver which has an input that is a blank black screen with relatively dark grey "MARANTZ" that prevents the screensaver from playing. I estimate the longest "on" period has been around or just north of two weeks (we neglect my mancave to an embarrassing extent). This seems still like a low-risk scenario, but I haven't had a problem with it yet. No retention and performance has been, as far as I can tell, the same.
