Hi,
XYZ is an absolute space, it doesn't take the adaptation of the
observer into account. Hence, the lcms function does not have
any parameter. If you want a modified XYZ taking chromatic
adaptation into account, you may use Lab, or better, an appearance
model like CAM02

interpretting this correctly?
Thank you for your help,

What range of values are you passing in as XYZ. I just tried and got
,, the cmsCreateXYZProfile doen't have an argument for the white
point. Excuse my lack of experience here, but how do I set the illuminant
and observer.
