OLED is the best screen tech out there currently. Burn in protection has improved a lot since early panels. We've had OLED in devices for many years now.
I've owned countless devices with OLED and used them for thousands of hours and I've yet to see burn in.
The only device I have that doesn't have OLED is my M3 Air. I wish it had OLED but it seems if Apple were to put OLED in it would raise the cost of the Air quite a bit and it's their entry MacBook so they will be waiting until it's cheaper.
I have 2 OLED tvs, oled iphone, oled steam deck, oled switch, my apple watch is oled, my PC monitor is OLED. Despite all my other displays being OLED the display on the Air is probably one of the best LCD i've ever used. The only downside is the glowing blacks. It's not really an issue unless I've got a lot of dark areas on my screen like when watching something with black bars.
Mini LED is awful and the sooner MicroLED comes out to replace it then all the better. Also then people will stop worrying about OLED even though it's a non issue for 99% of people. MicroLED is the only display tech that will beat OLED.
