First time I've heard of omarchy, that said often when I really don't understand the hype of a product I have to remember it's possibly just not for me.

I've been a desktop linux user since the 90's and entirely since 2003 (excluding gaming) so I'm not the target user.

Cute in the video on the omarchy page that they use Edward Hopper's - Nighthawks painting (~11m) - that was my default wallpaper for about 15 years on Linux.
