I'm not convinced. I have an iphone 14 pro which has a 120 Hz screen. I can absolutely see the difference when scrolling compared to my older iphone 11 or computer screens.

However, I'm typing this on my Dell monitor which only does 60 Hz. It honestly doesn't bother me at all. Sure, when I scroll long pages I see the difference: the text isn't legible. But, in practice, I never read moving text.

However, one thing on which I can't go back is resolution. A 32" 4k screen is the minimum for me. I was thinking about getting a wider screen, but they usually have less vertical resolution than my current one. A 14" MBP is much more comfortable when looking at text all day then my 14" HP with FHD screen. And it's not just because the colors and contrast are better, it's because the text is sharper.
