This control is principally for returning, in the image metadata, the CCM (Colour Correction Matrix) used by the imaging pipeline. By which we mean the 3x3 matrix that is applied to the camera RGB pixels after subtraction of black levels and white-balancing, but before any gamma transformation. Some implementations may also choose to let an application set explicit colour matrices, using this as a control.
