In my fairly limited expreience of flying to HKG it has been pretty full in J anyway.
Yep VS will only generally upgrade if they need to and IF they need to they have an algorithm of who to upgrade depending on status and fare bucket
They are quite stingy (yay) on giving free upgrades just because there is space available - was one on a flight that was full in Y and PE but only 1/3rd full in UC and there were no free upgrades.
On VS the general rule is that to be be in UC is to pay to be in UC
