And I still can't figure out if there was a 1985 remix of ROTJ, or if the 1983 theatrical mix was ever released on LD/VHS ...

I think this one will remain a mystery. My best guess is that as ROTJ was made with Digital Sound and the first release on Laserdisc has Digital Sound so I think they may be the same. By the time that ROTJ came out ANH and ESB had already had the 85 Digital Sound treatment.

I would also guess that those theatres that were THX capable in 1983 had a different mix to the one that more basic theatres had but that basic mix is what the Laserdisc got.
