I fear that such comments are similar to the old 'a monster cable makes my digital audio sound more mellow!'
The eye percieves at about 10 hz. That's 100ms per capture. All the rest, I'd have to see a study that shows how any higher framerate can possibly be perceived or useful.
Well if you believe that, start up a video game with a framerate limiter and set your game's framerate limit to 10 fps and tell me how much you enjoy the experience. By default your game will likely be running at either 60 fps or 120 fps if you're vertical synced (depends on your monitor's refresh rate). Make sure to switch back and forth between 10 and 60/120 to compare.
Even your average movie captures at 24 hz. Again, very likely you've never actually just compared these things for yourself back to back, as I mentioned originally.
Sure, that can all be true, and it still doesn't make 500hz make a particle of use.

It takes effectively no effort to conduct such a study yourself. Just try re-encoding a video at different frame rates up to your monitor refresh rate. Or try looking at a monitor that has a higher refresh rate than the one you normally use.

Not sure what this means; the eye doesn’t perceive anything. Maybe you’re thinking of saccades or round-trip response times or something else? Those are in the ~100ms range, but that’s different from whether the eye can see something.
This paper shows pictures can be recognized at 13ms, which is faster than 60hz, and that’s for full scenes, not even motion tracking or small localized changes. https://link.springer.com/article/10.3758/s13414-013-0605-z
From that, then, we conclude that somehow 500Hz is important or meaningful?
Modern operating systems run at 120 or 144 hz screen refresh rates nowadays, I don't know if you're used to it yet but try and go back to 60, it should be pretty obivous when you move your mouse.
