This is pretty much what I concluded as well after using my 43" 4K LG monitor for about 3 years. Lately I've been trying out my wife's 27" Apple Studio Display. It's smaller but the PPI is amazing...

You can achieve the same perceptual PPI by sitting further away from your 43" monitor.

The longer focal length is much better for eye health, with less stress on ciliary muscles for focusing.
