Short answer: no.
Long answer:
POV-Ray uses different techniques to calculate different mechanisms of
light transport. Raytracing is used to calculate the direct
illumination, Monte-Carlo radiosity for the diffuse lighting and photon
mapping for specular light transport. The combination of all those
results in the color of the pixels.
So how much light reaches a certain point in the scene can be found in
the pixel color. How accurate this is depends on the scene modeling and
the parameters used. How much light actually reaches a certain object
on the whole is not possible to derive from this though.
