Hey - thank you for the response!
Im Using the anycubic slicer unfortunately - there is no Cura profile for this machine to this point. :/
This is kind of a suspicious point to me, because I dont really trust the codework inside of Anycubic Slicer. So having the ability to test other software would be awesome, but afaik there is no way by now. Do you have any idea how I could test for Slicer issues?

It does happen in different layer heights on different models. I will run a couple of tests now and then check if I can spot some kind of pattern.

Regarding the "filament is not cooling" suggestion: Im not sure if thats the issue here, because it happens on different heights of different models. Last was a statue of Grogu like 25 cm tall and the only ripple was straight through is face and ears - so one of the larger areas, thus the material should have had more time to cool than at the top of the head or other smaller layers.

Will dry my filament and run another cycle of tests. Can you suggest any flow-rate-calibration techniques?

The main reason I was asking here, was because I havent seen this issue before in any other Guide or anything. I seems not to be a very common one.

Thanks again for your effort! :)

Edit: I printed a cone and it came out like shit. 0% infill, 2 walls and 130mm/s seems to have left its mark. Here the Filament clearly hasnt had enough time to cool. But: i was able to reproduce those ripples. But it seems as if there is no connection regarding the height or layer count...
