The Mother control room scene is a bit too saturated IMHO, but the BD is too pale - maybe something in between should be tested.
The Ash head scene made me think... as you wrote, Ash's top of the head is blue also in the BD, plus his shirt is not so pale when he is still "alive"... the BD seems to have the most natural color grading, but this should be not considered the "right" one... watching the 35mm frames, the LD it closer than the other ones, even if LD tends to blue and 35mm to green, but the others tend to be white.
(because I'm not using the usual display, and colors here are what they are, please take these notes with a grain of salt...)
