Sorry, I'm not going to go order a new iPad Mini just to test it in person, and even then if I came to the same conclusion as I already have based on the videos, you'll just revert back to "well different people perceive it differently" 🤷♂️ You've already said that about others on the forum who DO have the new Mini in their hands and say they don't see the issue (or think it matters). Seems to me this is pretty analogous with the OLED PWM phenomenon that bothers some people and doesn't bother others, but it's not considered a defect.
I understand that cameras aren't the same as our eyes, but neither are they drastically different. And, again, surely iFixit and other professional video producers would have mentioned something like, "By the way, this effect is much more pronounced in real life than you're seeing on video here."
I'm still not understanding one thing, though. Do you not pause to read things while scrolling? Are you literally scrolling non-stop the entire time you're reading? That seems very odd to me. Wouldn't you scroll, stop, read what's on the screen from top to bottom (or at least most of the way down) and then scroll some more? Seems like that would mitigate any possible "dizziness" because you give your eyes a break.
