I don't get this debate at all, LCD has less burn-in risk. OLED will always be an inferior choice if they can't fix its short lifetime. Or, I guess, this fits well with planned obsolescence: higher fidelity, shorter life time
What I don't understand is why there seem to be no "bulk processes". Saw a wafer into (tiny) pieces using a raster, somehow (yes yes...) load them onto a roller, and place them a column at a time. Anything resembling a pixel at a time seems wildly impractical. They actually seem to be that far I guess, because the price per LED is already down to ~0.05 cents ($10k for a 4K display). Lesson: 4K is a lot of pixels ;)
