The whole argument is silly. People coded on 21" CRT and LCD monitors at 640×480 even, and yes ... they still live!

While higher resolutions look nicer, they provide no real value for a console. I've had 4x xterms on my desktop for 30+ years.

There is zero "extra space" with higher dpi. None.

One sad downside of things looking nicer, is the battery cost.

UHD vs HD means 4x the pixels, and a GPU rendering all those pixels. If you want a 14hr battery, and light weight, you won't be getting it with a UHD screen in 2022.
