I'm on the other side where I've been buying Thinkpads partly because of the display. Thinkpads have for a long time been one of the few laptop options on the market where you could get a decent matte non-glare display. I value that, battery life and performance above moar pixels. Sure I want just one step above FHD so I can remote 1080p VMs and view vids in less than fullscreen at native resolution but 4K on a 14" is absolute overkill.
I think most legit motivations for wanting very high-res screens (e.g. photo and video editing, publishing, graphics design) also come with wanting or needing better quality and colors etc too, which makes very-highly-scaled mid-range monitors a pretty niche market.

Did you make a serious effort while having an extended break from retina screens? I'd think you would get used to it pretty quickly if you allow yourself to readjust. Many people do multi-DPI setups without issues - a 720p and a 4k side-by-side for example. It just takes acclimatizing.
Installed arch, setup some commands to underclock the processor on login and easily boost it when I'm compiling.
Battery life is great but I'm not running a GUI either. Good machine for when I want to avoid distractions and just code.
