What you say is correct for some, but not all people. In FPS games many don't see a huge visual difference between 60Hz and say 140Hz, except for latency. That's not true for everyone. For me and a few others, there's even a clear difference between 120 and 144 Hz, and to 60Hz it a gulf. A Refresh rate of 60Hz in a high paced, close up, fight becomes a bit of a where's Waldo situation. It's as if my brain stop doing motion estimation because the frames doesn't really fit together, so I kind of stitch together the individual frames and try to guess what next 'slide' is going to show up. I know there are a few other with the same issue, and anecdotally it might be a trait that occurs with some forms of ADHD/ADHD-PI. But I don't have a good reference on that, only experience and people I've met.
