The `lumacoeffs` input represents the luma coefficients of the current working color space. If no specific color space can be determined, the ACEScg (ap1) luma coefficients [0.2722287, 0.6740818, 0.0536895] will be used. Applications which support color management systems may choose to retrieve the luma coefficients of the working colorspace from the CMS to pass to the node's implementation directly, rather than exposing it to the user.
