Hi Gavin,
As you said yourself, the equation cannot be solved UNLESS you know both
variables on one of the sides.
In other words, you'd need to have the BG image in order to prep a FG image
so it can be comped in sRGB space and match the results of a linear comp.
So is there no way to output a
I knew I was right. (You guys just proved an old argument I had with
someone).
Oh, the joys of self gratification.

I hope there was a bet involved... :)
If you need further proof, you could use this script:
set cut_paste_input [stack 0]
version 6.2 v4
BackdropNode {
inputs 0
name BackdropNode2
tile_color 0x7171c600
label BG
note_font_size 42
selected true
xpos 2434
ypos 13246
bdheight 156
}
Truth is, I don't even remember who the argument was with - I just remember
being annoyed.
Thanks Ivan.

Essentially we have a situation where you would need to find equations for
u and v such that (xy + z(1-y))^(1-2.2) = (uv + z^(1-2.2)(1-v)).
