I think the general consensus is that the bluray is too orange, the WOWOW is more reddish, while the theatrical grading was more yellow. Although the 35 mm stills are too saturated, it's still interesting to see if the regrade is closer to those colors, than the bluray. Here are some comparisons (order: 35 mm, bluray, WOWOW, regrade):
The sky just doesn't look right in either the bluray or the WOWOW. It's supposed to be blue, like in the regrade. Also, particulary in the last example, the colors in both the bluray and the WOWOW are flat, too orange in the bluray, too red in the WOWOW. The regrade has a full spectrum of colors, and looks much more natural.
