What possible benefit does that have? It’s so far beyond the realm of human perception that it feels rather pointless.

The quicker the panel receives the signal to change, the less ghosting. Even if you can't perceive the individual frames the overall image will be more crisp because it transitions to the correct image sooner. Pixel changes aren't instantaneous, especially when going between opposite ends of the spectrum.

that "bigger number better" ~~mindset~~ delusion

The human eye doesn't work via a pulsed frequency and is working on purely organic electrical signals. Quite a few sensory neurons will spot each frame. Article says the eye can sense up to 20,000Hz.

If you measure response curves of individual cones and rods you won't see any of the parameters go below the ms range, probably not even below 10ms. However the retina does receive bright short pulses as longer averaged signals. All the very high Hz vision cases see information of the same "object" spread over many cells in the retina. A trail showing up as many distinct images vs a long smear.

If you couldn't move your eyes the limit would be lower, but because you can't the rendering cannot anticipate those effects and emulate them. Motion blur is what happens when you always "anticipate" the eye to remain static. If you could measure eye movement extremely well and react within well under a ms, you might be able to match motion blur to eye movement of a single person. Add a second observer and it already breaks down. Not that our sensors are anywhere remotely near making this possible.

Edit: I suppose this would mean if you integrated a display into contact lenses and got the latency right you would max out at lower Hz.

It really isn't. There's a whole lengthy explanation of it here but tldw motion breaks it. Lower refresh rates leave single images instead of smooth trails, while if you track motion then slower refreshrates make stuff blurry while in motion.

I don't think the video mentions it, but you could flicker the backlight to make tracked motion smooth, but then eye movements will see many individual images end up on your retina instead of motionblur.

If you wanna wiggle you mouse at high speeds while maintaining image quality, say for fps 180 noscopes, then you will easily see improvements into the 10s of kHz.

One easy way to see this of you are equipped for it is to drag a window around on your desktop at 60hz and then do it again at 120hz. The difference on smoothness is obvious.
