The fly in the ointment is the 1987/88/89 UK VHS Fullscreen tapes that you would expect to have the 1985 digitally remastered mix with the tractor beam line from the mono mix added. That line is missing so I am unsure what the mix on these releases is.
I cannot comment further at the moment and have no knowledge of the French audio.
