If you aren't already, definitely make use of your TV's pixel refresher (LG TVs) or whatever your manufacturer calls it. I have a 2018 LG OLED, and I usually run it once or twice a month.
I’m pretty sure that by default, LG Oleds run an automatic Pixel Refresher once you turn the TV off after 4 hours of cumulative screen on time. I read on the OLED sub that it isn’t a good idea to manually run the Pixel Refresher unless you’re seeing burn in.

Newer models? Mine is a 2017/2018 and I don't think it runs automatically.
