ICC's D50 vs sRGB D65 problems

[snibgo (Alan Gibson)]

Hmm, I’m scratching my head. Possibly dcraw is confused about what type of profile it is creating?

Exiftool says this about the ICC profile that dcraw embeds in my tiff:

[ICC_Profile]   Profile Class                   : Display Device Profile
[ICC_Profile]   Color Space Data                : RGB
[ICC_Profile]   Profile Connection Space        : XYZ
:
[ICC_Profile]   Connection Space Illuminant     : 0.9642 1 0.82491
[ICC_Profile]   Profile Description             : sRGB
[ICC_Profile]   Media White Point               : 0.95045 1 1.08905

ICC (http://color.org/specification/ICC1v43_2010-12.pdf) says:

For capture devices, the media white point is the encoding maximum white for the capture encoding. For displays, the values specified shall be those of the PCS illuminant as defined in 7.2.16.

So this is a display profile, so the media white point should be the same as the Profile Connection Space Illuminant. But it isn’t. I don’t know why.

Perhaps LCMS ignores the Media White Point. Certainly, when I use ImageMagick to use LCMS to give the chromaticities, I get the numbers in my previous post, D50.
