What should WIP software look like? There was a time when the 1998 beta for macOS, called Rhapsody, looked horrible and disjoint.
There was also a time when the iPhone looked like this - https://i.imgur.com/wwH2UoF.jpg

As for Rhapsody, that looked decent, it had a similar vibe to A/UX where it looks like Mac OS Classic but runs Unix.
Perhaps you are referring to Kodiak or Cheetah, but those were pretty GUI-consistent at that time. Granted, up to Panther it was just Aqua and getting it to work consistently and performant, but I don't think it was ever in the state that this RavynOS is. That's mostly because NeXTStep as a foundation already had an existing GUI that was consistent.
RavynOS is having a bad presentation because it looks like some sort of odd partially-done theme based on CDE/Motif.
I thought Rhapsody looked good.
95% of it is the fonts. Apple always does well with the fonts.
Yes, but you are straw-manning the argument. This is skankphone UI - a UI used by the technical team building back-end services and features for the original iPhone. The actual UI was being built in parallel, and obviously it never looked like that.
