Having just tested this with POV-Ray 3.6 (actually MegaPOV 1.2.1, but that
shouldn't change a thing here), I agree that this really looks bogus (well, the
comparison with a sphere shows that it definitely *is* bogus), and I'm quite
sure that this is a bug.

The good news is that POV-Ray 3.7.0.beta.32 does not seem to have it. With that
version, I found virtually no difference between the sphere and the parametric
(except for some slight jitter effects).

So you may want to try the current 3.7 beta for your experiments. POV-Ray 3.6,
at any rate, obviously isn't a reliable tool for your purposes.
