The monitor does not have that capability - if it did, it would be able to compensate for burn-in exactly. You would need to do weird things like point a camera at the monitor and have it diagnose and re-calibrate itself, but this would not be anywhere near exact so you'd still have quite a bit of noise. And everything you do to try and "solve" burn-in, other than turning the screen off, just adds even more burn-in!

You can sorta meet the burn-in half way with a smaller number of thermocouples (temperature is the primary component of burn-in AFAIK) and a wear model related to cumulative energy input. I've been looking to prototype this, but I've not done the work to acquire a panel which I could prototype it on. It'd take quite a bit of fast memory, but not an outlandish amount.

I hope I get a chance to take a poke at it before too many patents are filed.

Not talking external sensors. You already know the brightness of each pixel from the color information and panel brightness.
