So I had a look at the trailer for the 2017 Dolby Vision rerelease (https://www.youtube.com/watch?v=64IIfxDrhJY) and found that it has different colors to the 2012 release on the bluray. The colors seem to be a bit darker but with much less yellow. The seem a lot more natural to me.
Not only that but the trailer, while being an almost identical cut, is zoomed in by a small amount and while comparing using difference mode, many of the shots dont quite line up. This suggests the trailer was cut with a whole new master and not just a regrade of the current 2012 master.
I downloaded both the 2017 trailer and a trailer for the 2012 release from youtube and made this comparison image.

A future 4K HDR release should look pretty good with these colors, but that could be years away.
