Notice in the sample render how the domain bounding box is rendered in the reflection.
The domain is set to be Uber > Transparent = 1.0
It does not matter if Camera Visibility and Cast Shadow is turned on or off. Same result.
I think we could fix this in the core renderer, but like I said in the other thread if you raise the box a bit it should fix it.
Raising or lowering the domain does not fix it because it is the reflection of the entire domain that we're seeing. Not just an interference with the plane (which is a temporary fix for the cube example).
This happens on all other simulations that use domains as well. It is always present somewhere in the render spoiling the final image.
