I agree. Though I would formulate it a bit differently. You can live fine without HiDPI or >60Hz. But once you have used them for a few days, it's really hard to go back.

Our daughter still has an older iPhone with 60Hz and I cannot look at it. The flickery animations drive me crazy. Yet, I have had iPhones with < 120Hz screens for well over a decade.

I went back pretty easy. The real thing is the pixel viewing distance. At laptop viewing distances I couldn't see the pixels on the low res screen anyhow. The only real noticeable difference was ui text was a little bigger. Refresh rate you stop noticing fast. I personally can't tell when my m3 mbp is on 120hz on the power adapter or 60z on battery, maybe if I hunted for it specifically by scrolling at lightspeed.
