Good thing to note, @nick-shaw
1.1 was released in June of 2018. ITU-R BT.2100-2 was not published until July of 2018.
We can add this clarification in the 1.2 release.

@nick-shaw what sort of a comment were you thinking should be added here?
After reviewing this, I'm not sure if it's necessary, but I could certainly add something if you think we could make it clearer. Does your concern stem from the fact that 2100-2 declares beta
as a "variable for black level lift"?
The citation in the comment for the function ST2084_2_HLG_1000nits_f3
currently cites Section 7 of ITU-R BT.2390-0, where, in 7.2, it specifically says:
For both transcoding and conversion a black level for the HLG EOTF also needs to be specified. The HLG black level, LB, should be set to zero for transcoding and conversion.
Do you think I should add that statement?
