I like your ideas on this.  I'm fond of saying that Radiance is a
lighting simulator which can be used for rendering, rather than a
rendering tool.  Usually I demonstrate this by showing a simulation
image next to a Radiance-generated diagram of numerical lighting
levels, emphasizing the point that this is an attempt to approximate
luminous reality with some level of accuracy.

My approach here would be to overlay isolux contours on the unfiltered
image, and set it next to the filtered image.  Does this sound like
the kind of thing you're looking for?
