Interesting article here

https://www.techhive.com/article/3239350/smart-tv/will-hdr-kill-your-oled-tv.html

Since I don't have OLED not an issue for me but something to think about when I look at a new 4K TV.

Interesting read, but overly worrying.

His more reasonable estimate towards the the end of the article of a reduction to 80,000 hours is still a life long life.

I'd call myself a heavy user (for someone who has a fulltime job), so a generous estimate would be 40 hours per week. If my maths is correct, that's 38 years before it is down to 50% brightness.

So over 7 years to drop 10% (with the TV doing some clever compensation to deal with that 10%).

And in 7 years I'll probably be looking to replace it with whatever the latest and greatest thing is anyway.

There were similar (apparent) worries with Panasonic plasmas doing overly agressive compensation for aging display panels.

Basically the steps for bumping up the brightness as the panels aged was said to be too noticeable.

My old plamsa is used for 5-6 hours every day and is 8 or 9 years old and I cant say I have ever noticed any issues.

The theoretical lifespan of the panels exceeds any actual lifespan of the other components anyway.

(Hmm - with smart TVs the software will be junk long before the TV wears out anyway)
