So I’ve taken in a lot of feedback and I certainly agree with what everyone is telling me, I’ve been trying to figure out how to work with the print as there seems to be a fair bit of inconsistencies with it. Certain scenes look perfectly fine and others completely overblown with yellow, which compared with the better looking ones doesn’t match at all.

When I watched the first attempt at correcting the bluray yesterday, luma seems to still be the largest issue.

I just tried to match the bluray and print on that basis alone.
Turns out the results are fairly good, the print and BD doesnt perfectly match, so there is artifacting, it varies scene to scene.

Print before and after light matching to bluray.

I find the end results quite good & while they obviously don’t look all that great at the moment they will probably produce a better result to color match towards.
