A bit more about the gmic cubic look-up table (CLUT)  filter

   

As it states you need two images one before and one after. Unfortunately your small before / after images you posted are not geometrically identical, so you will have to do a bit of image matching.  Once you have done that and using gmic

(1) The two layers
(2) CLUT from before after
(3) Set the output mode
(4) Give the generated CLUT a name
(5) Set input layers to All

Ok that and it makes the CLUT

Now in your large image and gmic
(6) Apply External CLUT
(7) Find the CLUT just created
(8) Always a good idea to output a new file, just in case you screwed up.
