I just got back from a DCP 2k projection of The Dark Knight in Paris, France, and it was gorgeous. The Blu-ray, the DVD, the TV broadcasts are way off colorwise. The movie is tealer (almost nothing is really blue, from the very introduction logo to the night sky when Batman, on top of a building, hears he can find "Harvey Dent" on 8th and Orchard or when he stands on the ruins of the 250, 52nd street after Rachel dies), golder, browner (like Begins and Rises). Its colors are warmer and there was no edge enhancement. Also, it felt darker. The Joker's face when he removes his clown mask in the beginning wasn't as bright as it is on the Blu-ray, and so the details of his makeup were less visible. And finally, there was no distinction of quality whether the shots were shot in 35mm or IMAX. The DCP I saw was 2.35 all the way.

I don't understand how Warner messed it up on home video since a gorgeous digital master clearly exists.
