Nope, the prints don't have really lush colour, (but the GOUT colour pallete is way off in places) it is the camera taking the photos that is punching up the vibrancy at the Senator screening etc. I have a technicolour print in front of me right now, and the colour is nowhere near as vibrant. I have seen another Tech print, and prints taken from the french negative, and in all cases, the images aren't washed out, but aren't 'punchy' either.
Also, if you read interviews with the DOPs and others that worked on the film, they were going for a softer, more gauzy look, which fits in with how the prints look.
below is an example, Aussie Tech-IB on the top, grab from your front page on the bottom.
As I said, I like the look you are creating, but it is much more in line with a late 90s to early 2000s look, rather than how the originals looked in the 1970s.
Film just doesn't do those deep deep blacks, (negatives do of course, but the prints we saw in the cinema didn't).
The push towards deep (crushed sometimes) blacks and pushed whites is a more contemporary taste, it wasn't popular in 70s cinema.
