are you sure? The lower sides of the holes still seem to be darker.

It appears to me that your camera is looking "down" from positive y
axis, and I'm not really sure what the default camera rotation is then.
You might wish to specify an explicit "up" vector for the camera.

Just for fun, you can also take you existing image and rotate it 180
degree in an image processing program to evaluate the effect.

It might when used with the area_illumination keyword (requires 3.7 RC)

This may depend on how "rounded" the edges of the holes are modelled
in the mesh. If there is just a mathematically perfect angle they will
not show a highlight.
