Try non-linearised gamma of 2.4 for Rec 2020.

Some discussion of this on #892.  Also influenced by discussions
with Dennis (email Tue, 30 Jun 2015) on how the oft-quoted
(e.g. by Wikipedia) gamma functions are camera transforms and not
intended for uses like ours.

Also see ITU-r BT1886 which talks about a gamma of 2.4.
