Is there a way to get an image of which parts of a render took the most 
time? Maybe blue for fast areas and red for slow areas? Does this make 
sense?

There used to be a CPU utilization histogram feature in POV-Ray, but they have
removed it in 3.7 for some reason.

In version 3.6, there was an hystogram option. It would output a gray 
scale image showing time to render a block. Could be set to some 
arbitrary block size down to per pixel.
It was removed from 3.7, possibly/maybe related to the added support for 
multiple CPU and cores.

That sounds like such a cool feature!
