It absolutely does have well-defined chromaticities.

LCMS specifies an odd value for D65 and doesn't compensate for hexadecimal rounding. And so almost everyone who distributes ICC profiles made with LCMS makes AdobeRGB1998-compatible profiles that don't exactly match the Adobe specifications.

Graham Gill distributes ClayRGB1998.icm that exactly matches the Adobe specs. I've submitted code to GIMP to make a proper AdobeRGB1998-compatible profile.

Other free/libre profile makers really aren't distributing an exact match to the Adobe specs. I've already reported this on the LCMS mailing list.

Similar problems obtain with a lot of other free/libre ICC profiles.
