I've also done some image search and it does change a bit with apps and they look quite good. So I'm still baffled why this aversion to images is decided. Or just overlooked maybe?

Hmm, I haven't noticed any difference. Which apps are you referring to?
Is that the default?
Furthermore, I'm interested in what their solution for email, calendars, and all the other Google services look like. If it's AOSP, that's a good reason not to use this ROM. I suspect it's not actually using AOSP's apps, though.
There are no built-in apps for that. The only custom apps GOS provides are Auditor (https://attestation.app/), Camera, Calculator¹, Contacts¹, Files¹, Gallery¹, Messaging¹, a hardened PDF viewer, and Vanadium (a hardened version of Chromium). Everything else is up to you.
¹) AOSP app or fork of the AOSP app.
