Morning Departures are not good flights ex HKG for yield (I used to be in a commercial position with CX studying this route).
The ANZ, QF and CX morning flights are full of Australia/Kiwi transit pax, which is generally low yield.
That is also borne out by a recent Trip Report someone filed from a trip HKG-LHR on NZ39, I think they had most of a row to themselves in Y.
That said, I usually have terrible trouble sleeping on planes - yes, even in the Suite - unless I totally wear myself out first.
Even then, the danger is that I still only manage to sleep fitfully, or not at all, so I will often take daylight flights, to avoid feeling like death at the other end.
