I suppose it depends on the individual and the person use case! Switching the TV off every 4 hours to do a recycle, and vary your content is not a big deal in comparison to using say a acoustic guitar. I play the guitar, and you really do need to nurse them. Replacing strings, re-tuning, oil the finger boards, dealing the humidity levels etc, etc.
The technology is fine for my needs. As far as I am aware 2019 panels onwards should be fine. I know multiple owners using LG oled tvs as gaming monitors, and no issues three years down the road..
Plasma had the same label as Oled back in the day. My Sammy Plasma went 15 years without burn-in issues.
Again in my use case! I was never one for sitting down to watch the news channel all day. I find the content depressing. High end TVs for me are for Movies, box sets, and Sports..
