I am sure it is a great calibration system, certainly better than anything I have access to, but that is a very small difference.
6504K is 0.31271405688264758 / 0.32911909913718723
6500K is 0.3127788761948111 / 0.32918349849804096
D65 is 0.31272661468101209 / 0.32902313032606195 I believe, but don't quote me on this as I have not run the calculations myself and therefore have no guarantee of its accuracy.

So that's a difference of 0.00006481931216352. I guess we will have to make do for now then.

Seems to work fine if I omit the grayscale information. What I'd do in your case is use good software such as ArgyllCMS to calculate the transformation.
