It has TL and TR. The issue is that it’s an analogue format that I’m not sure is really designed for digital? I know in other 35mm release people just leave the Dolby SR tracks as 2.0 - but do they decode correctly in a home theatre? This I don’t know partly because I don’t have a home theatre with surround sound in which to check.
In that case, just look at a Criterion Collection BD 2.0 channel encode. Maybe that’ll help with the specifications.
