Transfer function for "ICtCp" should vary with method (PQ / HLG)
See original GitHub issueIssue Description
https://github.com/colour-science/colour/blob/02b595b26313c4b4f55adc41d599f90c4c9edbcd/colour/models/rgb/ictcp.py#L192
This appears always to use eotf_inverse_ST2084 but should in fact use oetf_HLG_BT2100 if method is 'ITU-R BT.2100-2 HLG', according to the November 2020 revision of Rec. ITU-R BT.2100-2.

It may have been incorrect, but it existed in a published version of the paper. What we try to do with Colour is enable people to match any other implementation, current or historical. If somebody needed to match the processing in an application version released while the old matrix was published, they would need that option.
Yes! 😃
