People seem to forget that the photos Mike posted was from a screening using a warm 70's bulb. If Harmy had wanted it to look like that, he'd have to add a warm curve to the whole movie.
I also remember Mike saying that the only thing that could be 99.9% trusted in those pics (if aiming for a 70's projection look) was the hue.
If I remember correct, Harmy was not aiming for a 70's projection look, but the 1977 version "remastered" to today's standard which is not as warm.
