Hello,
I've updated the scenes with a slit (air gap).
Both deliver the result that I would expect while having this air gap.
This is the result of the light path scene (hope this one works out of the box):
This is the result of the two plastic parts:
However, I'm still looking for right setup, leading to right results, without such an air gap.
I read the posts about the world and the camera space.
Maybe I'm to stupid to get the point of it, but the geometry is not far away from the origin and the parts are not that small that this effects should appear, also the camera is only few meters away.

I'm not sure how to explain them but there are two things that needed to be followed first or we might not able to isolate it further. For the Objects Surfaces did you give them a 0.1mm spacing? Can you try and then compare it again to your reference Single Layer?
I hope this will help to isolate the issue.
Thank you for all the effort that you did.
with best regards
