DUCCS: REC 709 preset gamma value? (NETFLIX requires 2.4)

Hi there

There is a REC 709  preset in DUCCS. I cannot adjust the Gamma. What is the default value?

Otherwise, what are the primary values and white point for REC 709, so I can make a custom profile?

Partial reply: 

Primaries are:

White point at CIE D65

Explanation:

REC 709 gamma is normally given by a composite function, linear for low Luma, then logarithmic (or exponential, I´m not a math teacher). Nevertheless, networks issue different specifications. NETFLIX requires a simple 2.4 gamma function. So what is the default vallue in DUCCS? And, if it isn´t 2.4, can anybody provide the primary values in order for me to make my own NETFLIX preset?

Thank you
