Although, on that previous screenshot the comparison was done with 
'emacs -Q', meaning it excludes customizations and shows the default 
look on my system (Ubuntu 20.04).

My actual customization looks weirder how: the font became narrower, see 
the attachment.

And this effect can be reached with just

   (set-face-attribute 'default nil :height 110 :family "Inconsolata_dz")

I like the mode-line better on this screenshot, though. *shrug* Just not 
the rest of Emacs.
