I'm not excellent in color theory, but in general:
- camera responds to any visible spectrum signal
- and, also, on UV and IR wavelenghts too.
So, triangle angles (bayer primaries) may reside outside of 'human eye locus' on xy 'visible colors' diagram (to include as much as possible colors into triangle).
The values you calculate from camera color profile data to be derived from profile creator's intention (color gamut, etc), not real 'bayer primaries'.
