I expect it would be on par with CRT tech in both respects, just for also having electron-excited phosphors. It seems OLED + everything ultimately competes with CRT for contrast/color/speed-- rather like programming languages' best-case compute performance usually being "nn% as fast as C." The least optimal thing about the image (for me) was it not being perfectly rectangular and stable, while everything else nails that right down, including this.

It is pretty neat... the market turning away is roughly as disappointing as a phosphor-based flat display is appealing. I feel like its reduced complexity and power usage could make it ideal for HMDs-- if/f it shrinks well. And probably nobody cares. :shrug:
