So chances are it works by overlaying zillions of shifted variants of
the pigment ;-)
I presume that somewhere in the process Sam used the input file to drive
a color_map or such. In that case, unfortunately HDRI colors are
"wrapped" to the 0..1 range. In that case the macro would need a major
overhaul to make it work with HDR images.

No. Those are only a part of the scene where the parameters of the
luminous bloom are set.
Just using the lb5.pov, from Samuel T. Benge, scene file that does a
luminous bloom post process on a previously rendered image.
