YMMV, but I use 40" 4K TVs and monitors like this all day and find the pixel
density at 100% scaling about right (Linux and macOS, not sure how Windows
is).  You can't necessarily focus on all of the screen at once, but often
there are things going on (like a compile I'm keeping an eye on, or a web
page that I'm comparing to some other thing, or an enormous GUI in some CAD
package) that use different parts of the screen at different times.

If you run one app maximised the whole time, and especially a text editor, I
can see that would be less than comfortable.  For instance, I'm writing this
in the middle of a 40" screen and the 80 text columns are 14cm wide and the
window is 27cm tall.  Meanwhile I'm watching a compile, and have a web
browser, some PDFs and a CAD package on screen at the same time.

40" 4K is now the standard issue monitor around my office, for similar
reasons.  My work monitor is an early 4K Samsung TV, which I wouldn't
recommend because it's laggy and the 'TV' stuff gets in the way.  But it's
OK if you don't mind a bit of lag, and if monitors are unaffordable...

I recently added a high DPI mouse as well, which makes pointing at things
across 4K a lot more pleasant.
