I'm sure no one doubt that, but we were talking about real life here...

This is exactly what i was talking about, in real life highlights (which i
would define as the bright spot appearing on on illuminated shiny
surfaces) are caused by reflection on the surface. Whether the reflection
is blurred or not (in other words how rough the surface is) only
influences the characteristics of the highlight.

With your definition of a highlight, that is correct. I don't know what
the actual definition of a highlight is, but when I see a light bulb in
a mirror I usually don't think of it as a highlight.

Huh? I don't see why interferences are only detectable less diretly than
cars, trees and planets, but that's merely a philosophical question of
course.
