When I open a document in Adobe RGB, which uses a white point of D65, and allow Affinity to convert it to my working space, which is Colormatch RGB (D50 white point), and have the rendering intent set to Absolute Colorimetric, I don't see the expected blue-ish tint in the whites. Absolute Colorimetric should NOT maintain the white point, and thus, a white in a D65 based color space should shift slightly towards blue when mapped to a D50 based color space. (and this is the behaviour I have observed in the past, using Photoshop)
Is the rendering intent setting even used when opening a document and converting to the working space? If it's NOT used here, when is it used?
