I strongly doubt they ever used the Tech print as a color reference since ANH 97 SE was screwed up even in the theaters from what I've heard.

You see, the first thing I thought when looking at the colors of the ANH 97 SE releases and digital broadcasts was "why is the whole thing tinted cyan?" except for the Mos Eisley part of course.

Then somebody made a post which I can't find now, about how he/she and a photographer friend went to see it in 97 and the photographer mentioned there was a lot of cyan.

So yeah, if they had used the Tech print as a reference it would've looked way cleaner and better.
