Comment (by Andrew-R):

 speaking about xvYCC I found two documents:

 https://www.researchgate.net/publication
 /250999893_192_xvYCC_A_New_Standard_for_Video_Systems_using_Extended-
 Gamut_YCC_Color_Space

 and preview/sample of  iec-61966-2-4 (it works as of today, I saved it
 just because)

 https://cdn.standards.iteh.ai/samples/14431/9e5a80b3c1a54ad0866f818def33466c/IEC-61966-2-4-2006.pdf

 so it seems those opto-electrical and inverse transfer functions are
 simple, but defined as 3 separate segments?
