If present, the cICP chunk specifies the colour space(primaries), transfer function, matrix + coefficients and scaling factor of the image using the code points specified in [[ITU-T-H.273]]. The video format signaling SHOULD be used when processing the image, including by a decoder or when rendering the image.
