I don’t get it… What is there to learn? Each LED has its own lifespan, so the more it’s used, the less bright it is. Only IPS and the like can have more or less constant wear out due to equivalent use of all backlight LEDs.
In fact, HDR panels with gazillion zones have the same problem, or at least they must have it. Though in case of HDR panels LEDs should be replaceable.

man, you hit all the main points correctly but mangled this part so bad
IPS has nothing to do with the backlight. it’s just a type of TFT among many. the exact technology of the liquid crystal layer doesn’t matter to how the backlight works.
at a basic level they’re all just a light behind with a layer in front to selectively block the unwanted colours. either layer can have different technologies. they’re not directly connected.
backlights can be uniformly lit, they didn’t even used to be LEDs at all. then they became single zone LED backlit, then they got more and more zones.

technically, sure, but practically speaking it’s effectively nonexistent under all but the most extreme (or defective) circumstances.
there’s a reason why microLED displays are the holy grail of display technology. all the benefits of OLED with all the benefits of being inorganic.
Yea, and mini and micro LEDs aren’t going to fully solve this either, because they have the same problem, just on a slightly longer timescale. The only way to really “fix” this is to have per-pixel auto-calibration, which is going to be really difficult

Sensationalized headline, nothing more.
The point is that OLED has worse burn in rates. The only screen I’ve ever had to do that was OLED and within 2 years of purchase with light use
