You're good, Warp.  :)

No, I don't have assumed_gamma.  I added it, with a value of 1.0, and things
are better, but not perfect.  I ended up lowering the image_map's ambient
value to some screwy value (0.57) to compensate.  Not sure why this is.

My original image has no specific assumed_gamma value, either.  Naively, I
would think if I have identical assumed_gamma values in my original and my
're-rendered' scene, shouldn't I get the same color from each pixel?

Were I to add an assumed_gamma of 1.0 to my original image, I would not
expect any improvement, since originally both renders lacked any
assumed_gamma setting.
