"Micro LED" is a relatively new display tech that's pretty much the same idea as OLED but made with metals instead of organic materials.

Yes, the microLEDs (I've heard of) are InGaN on Sapphire which are diced and placed in arrays. Apple bought a company doing this several years ago, but the densities they are capable of (30-100um pitch) and yields (1dppm?) are not a match for head mounted 8k displays (100mm/8000 = 12um pixel =>6um subpixel).
There are microOLED manufacturers like eMagin which integrate the active matrix into a Si substrate and use a color filter over white OLED, but even they are limited to ~2k RGB (per eye) at 9um pitch.
