Yeah, i've had a careful look between the different editions on capaholic and it really comes down to a faceoff between the german extended blu-ray and the japanese extended blu-ray, which the japanese blu-ray clearly wins with more retained detail, grain and better flesh tones than the german blu-ray. All the others are just totally overcooked or in the case of the dutch blu-ray has unappealing fleshtones and strange colour grading in general.

Yeah, there is definately detail there on the japanese extended blu-ray waiting to be brought out, I can see how you could make this work. Have you done any tests to see how it looks with grain added?
