What do you expect? It's only a guess at the normals, after all.

Yeah, and how do you know the normals of those triangles? By
interpolating between vertex positions (which is the only info
available to the hf code) or are you using info from the generating
pattern?

Aside from a different kind of interpolation (higher order), not
really.
