@prrace I know that the CSR description is not part of the specification. But I would like to point out that we do not specify built-in profiles as singletons (but currently implemented as such). Therefore, it is not necessarily true that the same profile will always be returned by `getInstance` method.

>The built-in profiles are singleton objects, if an application modifies a shared profile object via ICC_Profile.setData(), then the modified version of the profile is returned each time the same built-in profile is requested via ICC_Profile.getInstance(). This would impact all color space transformations using the modified color space.
