Limit the iPhone 13 Pro refresh rate (dizziness)

I noticed something strange yesterday. On my iPad Air (2020) I am not suffering dizziness when scrolling up and down, but I am on my iPhone 13 Pro.

I initially wondered if it was the screen size, but then I discovered that I could limit the refresh rate on the iPhone by going to Settings / Accessibility / Motion / Limit Frame Rate.

The difference when using the iPhone for me now is huge and even though it does not make sense on a technical level, it works for me. How bizarre...

This thread backs up the above.
