Try painting a probe in photoshop, I found that the resolution did not have
to be very high so long as the parts of the image had natural colors and
the correct density. It may be different on POV, I used 3dMax to do it
about a year ago so the renderers are totally different. 

There was one other issue I noted at the time, the HDRI source sphere needs
to be scaled correctly for the lighting to work correctly for small
objects. Try the St Peters probe again with the scale being closer to the
size ratio between that huge building and the tiny toy car.
If my words are not making any sense, tell me and I will draw what I am
thinking.
