This of course depends on how you define 'highlight', but you can surely
see a bright spot on a mirror ball when illuminated by a light source like
the sun.

The reason for using specular/phong models to simulate the highlight
effect is not only to avoid calculating blurred reflection but also
because you commonly use invisible light sources.
