I wonder if Mr. Harris can find out any information about the source of this 4k scan? Apparently, UCLA has a full compliment of materials for this film in their archives from a full and complete restoration they did back in '09. I'm guessing that's half the work. The other half being the actual 4k scan and careful, respectful mastering of the DVD/Blu-ray. And Olive has been known to just use what is given to them as the final product - sometimes good, sometimes not.
