No, cam_xyz is taken from the standard data, ColorMatrix2 is taken from the particular dng file.
At the time we put the standard data into adobe_coeff under "Canon EOS 6D" the matrix that Adobe had in their profile was not particularly good. You can replace the matrix with the one you prefer and recompile.
