Thread 2/4: The other display seems to be an improved 32 inch Pro Display XDR. Despite the lack of branding, It can be assumed at the very least that this display will be Apple branded.
Thread 4/4: This of course does not rule out the possibility of custom silicon for these displays. It simply means that there is no sufficient data proving otherwise. Finally, the 32 inch and 27 inch monitors seem to have miniLED displays and a 120hz variable refresh rate.
