Just going back to the screengrabs on page one, I like the look, but it is more like how Star Wars would look if graded for today's audience, and is way more contrasty and way more saturated than any of the prints.

That isn't necessarily a bad thing, people expect and prefer that look now, but the 70s prints are much less saturated, which was common in films of that era. If you want to recreate the original look, then you would need to change the grade a lot. But if you want a pleasing, more lush look, then this is great, it is really rich.
