Creating a LUT from the difference between 2 files

Merry Christmas!

I have a little lut question:
Is it possible in Lightspace to create a lut from the difference between 2 tiff files?
for example if I export a frame shot on RED using two different R3D parameters,
can I create a lut to mach them, similar to ARRI luts?

My situation is I have shots from RED camera that had VFX applied on them.
the VFX artist worked in redlogfilm gamma, while my grader wants to use the source gamma for his starting point.

Not sure how farfetched that is, thought it's worth a try.

Hi Amit, that's a function of MatchLight IMS.

Have a look at that product.
