After analyzing the BD, it appears that the creators DNRed the film grain out (due to the digital hybrid nature of the source) and then added fake film grain over it.
I have kept it in with AV1's FGS, but there is a bat file you can run if you want to remove it (does not delete originals)(and it also removes all the track tags for some reason...).
