Re: color timing. The short answer is yes. The long answer is it's complicated.
This color timing is based on a professional scan of a high-quality low-fade print, so it's closer to '77 colors than anything else you've probably seen since the 70's.
That said, there's a little variation in different types of prints, how faded or abused they got over the years, different projector bulbs, etc, making every theatre viewing unique, even in '77. Also, Harmy was starting most of this from the Blu-ray timing and sometimes he might not have been able to approximate the '77 timing perfectly from that source. But it's damn close.
