You know, now that I think about it, OLED (if not some other technology like microLED) might be the way to go for the next upcoming headsets. Sure, the resolution wouldn't be as high as LCDs, but this generation's LCD panels in the Index and Rift S are honestly high enough to not produce a distracting SDE anymore in most games. With next gen OLEDs, the pixel density and fill may reach this level, and I'd be satisfied with that. The contrast ratio and colors of OLED are missed and do in fact greatly impact games like Alyx where there are a lot of dark scenes.
