Have you actually tried using a light_source to see the results ?

In POV-Ray light_sources are not visible to the camera. Because
of this they should not be visible in the mirror either.

It sounds like phong highlighting in the finish statement. That
is usually the source for spots like that. You may need to make
a custom finish for your particular application.

It is really the phong, seems to be normal for this texture.
I have to use phong_size 500000 to hide the spot.

You can also lower the phong number instead of the phong_size to
influence it's affect on the finish i.e phong 0.25 phong_size 200
