You can find comparisons between the DCP and DVD releases on caps-a-holic.

If those are the real thing, then I stand by what I've assumed. The DVD is a bit warmer, hence a bit better, but the difference is so little when they're not side by side that it doesn't affect the viewing experience.

There are/have been 35mm film cells on eBay UK that could be helpful at determining color, even if it's not the same as projecting them. (Also, the auction pics are low res.)

How would a picture of a picture be helpful for that?
