I think another thing to keep in mind is that there’s probably an element of sensory adaptation at play here. Like when you wear a watch: you notice it at first, and then you don’t notice it on your wrist anymore.
So if you’re actively moving between a high-refresh-rate device (like a lot of people here with their 144hz monitors) and then one with a lower refresh rate, you’re probably more sensitive (and potentially annoyed) by the discrepancy.
You will notice this as soon as you use a low dpi device again for any length of time. First 10 minutes you see the pixels. After that you stop seeing the pixels.
Viewing distance plays a factor too. I realized 4k tvs are useless to me because I can't perceive 1080p pixels unless I'm comparison shopping in a TV show room from 2 feet away (probably why they don't let you experience appropriate TV viewing distances in these spaces in the first place).
