I assume a “professional calibrator” will have access to professional-grade equipment, like $5000 spectrophotometers.

Yes, which ones did you paste? Paste them here.

It's possible I made a mistake (there was one mistake I have corrected), as the direction of rows and columns is different - it's a painful process.
What I am really trying to say, is this is not easy, and frankly I'm not aware of anyone getting it working properly (correct me if I'm wrong.....PLEASE!!).

Works fine here, even brilliantly so.

Oh, and 6504k vs 6500k....um....really? Even 6600k or 6400k are basically invisible to the naked eye without a reference....unless you are leeperry
My CRT projector's response is messy (even with hours spent tweaking the colours with HCFR and Gamma on the PC...it's...old..) and it still looks fantastic.

1/1/1 in 6500K is equal to 1.0001484002173517 / 0.999984246706869 / 0.99971868953766008 at 6504K.
That is, at 16-bit scales, 65544.7254082441436595 / 65533.967607934659915 / 65516.5643188505533428, a difference of 1-20. Regardless of whether or not you can see it, it's a notable enough margin when calibrating a 16-bit gamma curve.
