Is there actually a fundamental physical limit in modern (O)LED displays not being able to emulate that “flicker”, or is merely that all established display driver boards are unable to do it because it isn’t a mainstream requirement? If so, it would still be much cheaper to make an FPGA-powered board that drives a modern panel to “simulate” (in quotes because it may not be simulating, instead merely avoiding to compensate for by avoiding the artificial persistence) the flicker than bootstrapping a modern CRT supply chain?

My LG has something like that, OLED motion pro. I believe it displays blank frames given the panel runs at higher than 24fps. Medium is noticeably darker but oleds have plenty of brightness for my viewing space and it makes slow pans look much nicer. High is even darker but adds noticeable flicker to my eyes

The reason why this is a difficult problem is that physically emulating the flicker requires emulating the beam and phosphor decay, which necessitates a far higher refresh rate than just the input refresh rate. You'd need cutting-edge extremely high refresh rate monitors. The best monitor I found runs at 500hz, but pushing the limits like that usually means concessions in other departments. Maybe you could do it with that one.
