Of course you’re right.As with almost all aspects of perception, there are significant variances in how human brains process movements, and in how prominent or distracting certain effects are to the individual person. This is largely independent from how good your eyesight is. I have very bad eyesight but can’t not see the jelly scrolling and be irritated by it on the mini 6.
In my case I rarely scroll far or fast. It’s mostly a note-taking device (NotePlan) or horizontal reader (Kindle). The rare times I scroll something a long ways or quickly, I get sort of a “ooh, is that the jelly thing?” And then I play back and forth a bit but can never really convince myself I’m seeing it.
Perception is neat.
