The 2D BD has a nasty reddish look but no problems related to brightness or contrast that I'm aware of.

So this is an ideal candidate to be treated with ColourMatch.

Not sure how ColourMatch works exactly, but could it recover lost grain (to the extent that it existed on LD)?

No, the script attempts only to apply the same color grading to a given source, using a color reference. But it's always possible to add some grain after that, even if I'm completely aware that it will never be the same.

Or, simply put, I could always use the laserdisc capture and upscale it... the last results I achieved are quite good, and should work even better with animated material. Further tests will be conducted after the laserdisc captures are done.
