[dizal]

Photoshop 26.8, Mac OS 15.5

From a CMYK images:

Export CLUT Layer as an ICC DeviceLink profile;

The CMYK ICC DeviceLink profile is created but, the OUTPUT curve are inverted.

See attached picture: LEFT: correct output curves. RIGHT: Output curves of the ICC Devicelink profile exported form Photoshop are INVERTED.

So, when loading the ICC devivceLink profile as CLUT Layer or doing a Convert color using the deviceLink profile, the color are inverted.
