Comfortable to UHD resolution than FHD? Is there a noticeable difference?

Greetings to all!

Puzzled by the choice of a new laptop, I noticed a few models from Lenovo/DELL. But in these models all top configuration go to display UHD (3840x2160), the models in younger displays FHD (1920×1080).
Display size 15.6 everywhere.

Currently working for 15.6 with FHD, and probably, if you look, you can grain to consider is the meaning to take UHD, but related somewhere write that there is a difference, somewhere write that a lot of flaws in terms of scalability and performance.

In fact, those who have experience of using and comparing both options, please help to answer the following questions (share your experiences):

  1. Will there be a noticeable difference when working with text, for example in PhpStorm, Notepad++, Terminal, etc. - all with web development? In movies/serials? (I don't play games)
  2. Will there be problems with the scalability of programs? In the same PhpStorm, Chrome, etc.

You forgot the most important operating system.

With zoom 150%, I faced problems in old programs and written in QT

In all other norms.
Thanks, updated the question. OS will be Windows 10.

You have problems in Linux Ah? - marco commented on April 4th 20 at 01:03
@marco, my problem was in Windows 10. Emulator mac too, but there not essential.
In Linux all the trouble, xorg have this stupid habit of rounding everything by a few pixels. - Marcia18 commented on April 4th 20 at 01:06

In PhpStorm UHD I would say the minimum comfortable resolution.

even fhd on a 15.6 - excess
more, of course, no less.
The text will not be noticeable, when watching movies the difference is not really distinguishable
