I recently bought a 1440p screen (for productivity, not gaming) and I can fit so much more UI with the same visual fidelity compared to 1080p. Of course, the screen needs to be physically bigger in order for the text to be the same size.
So if 1080p->1440p is noticeable, 1080p->4k must be too.
Like I said, 2D things it is noticable only because it makes everything smaller (there is more space because the elements inside that space are smaller). However movies and 3D games? No difference.
4k is noticeable in a standard pc.
