I'm sure there's a good reason why you can't get small 4K sets yet. The only real benefit would be HDR unless you were literally nose right up to it.
I'm talking about TV screen size vs resolution here. These sites suggest small hi resolution
TV sets aren't really worth it.

We're clearly not going to agree. You may well be correct about 4K monitors displaying small text etc, I haven't used one but I do have a 55 inch 4K oled tv that I sit about 4-5 feet away from and I'm glad it isn't any smaller as the 4K benefit would be reduced imo.
You're also underestimating the subjective benefit that HDR brings, far more than moving from 1080 to 4K.
