The blu ray looks darker than the dvd and they are from the same master, very weird. I will say the blu looks more film like, and the white color of roger moore's skin in this screen cap looks blown out.
About the wrong colors and blu tint in some of the films, Lowry also messed up the colors on the wrath of khan restoration. The uniforms look orange instead of red. Some scenes have an awful blu tint that was not their before.
Really a shame since the film in terms of clarity has never looked better, just like their work on star wars.
