To be a bit more specific:
I've gone into an existing .bpd preset (sRGB) and modified the primaries to reflect the Display P3 primaries (based on
https://en.wikipedia.org/wiki/DCI-P3), and kept gamma at 2.2. The latter as I understand it, should also match sRGB ("Pure Power"?), but it appears one can only specify 2.2.
The link to Wikipedia doesn't seem to work, so I have no idea what values you have used - But the correct values are within ColourSpace for P3 D65.
And I do not understand the comment "kept gamma at 2.2. The latter as I understand it, should also match sRGB ("Pure Power"?), but it appears one can only specify 2.2." What do you mean exactly?
But be aware of the above info on Apple using the wrong Encoding EOTF.
The result (from a 17^3 raw profile on a 32BP95-E probe matched to CR300) is a LUT for which primaries more closely resemble AdobeRGB than they do P3/2.2: the reds are more pure red, and less saturated/skewing orange as they appear in Display P3.
The native response from any wide gamut monitor will nearly always be a gamut that is not any standard colour space, and will be close to a 2.2 power law - all screens natively are a 2.2 power law EOTF - that is how they are manufactured.
Any further help?
