I have the same displays as you- Dell 4k @ 15" and currently using a 32" 4k (I sit 2ft away from it). I also have a Macbook Pro 16 (3072×1920). I honestly don't see a substantial difference between any of them, and I'm generally pretty picky about resolution.

Right but if you scale the 32" so you get the hidpi sharpness (and put it far away), you lose the real-estate that you could have on a 32" screen.
