How can you know it is not bias? For what its worth you might have never noticed any difference if you didn't knew they weren't refreshing at the same frequency.

For those of us who can see it, they are very noticeable. And could be told in blind testing 100% of times. After all 240Hz is still 4.1ms per frame, Again I have to point to this Microsoft Research Video.

Oh for me it's very clear.
Specially between 60hz and 120+.
Scrolling looks blurry/ghosted in 60hz.
I guess I could vibe code an app to set monitor Hz randomly in either 60 or 280 and test.
But it would be a waste of time from how clearly I can tell the difference.
