I strongly agree with dvdmike: if WOWOW has not the *right* color grading, surely it's better than BD...
...It seems to me that WOWOW has more details than BD - it could be used as source for a project, taking BD scenes (color graded) only when WOWOW has the *corrected* version.
I agree. It would interesting to see a three-way comparison of the BD, WOWOW and THX WOW.
