I don't think you need to do this for a second - what's on the disc will be 709. That's how blu-rays work, unless they're the oddball Sony 4K thing. The whole purpose of colour grading is to put whatever comes off the film scanner into 709.

If you haven't already, it might be worth tackling this from another direction. Look at the credits for the remaster, figure out who was involved* in doing the actual work, and shoot them an email or message? "Hi, I have a copy of the {WHICHEVER} bluray, can I pick your brain about the colorspace / film digitizing†process you used? (if it wasn't you, who would you recommend I ask)" Their answers might make it easier to figure out which dials and levers to adjust, colorspace or otherwise, if your 601-to-709 experiment doesn't produce acceptable results. They might be interesting from a process perspective regardless. Cheers, Rob *†: I can think of a case of a 90s Paramount series that was shot on film, but which also used a modest amount of CGI to augment the remastering of VFX- whatever CGI they used presumably was done to match the film in color-grading terms. If this case is the same as your case, perhaps Wade Felker or Dylan Hucklesby might be good places to start.
