Looks like the tier points for upgrades has be sublty updated in section 14 here
To get full tier points it now looks like you have to call and upgrade (before 24 hours?) and specifically request a non-promo upgrade or upgrade a reward ticket with miles. Sneaky change - i was planning to take up upgrade in the app to renew.
14. Flying Club Members will receive Virgin Points and tier points depending on the type of upgrade, as follows:
a) When you purchased a revenue ticket (not using any Virgin Points), and you upgrade to a higher cabin using Virgin Points, you will earn Points and tier points according to the original fare, before the upgrade.
b) If you upgrade your flight with a promotional rate (online or through the website) or via Your Bid, you will earn Points and tier points according to the original fare, before the upgrade.
c) If you purchased a full reward ticket with Virgin Points and you upgrade to a higher cabin using more Points, you will earn tier points for the upgraded cabin.
d) Members who have purchased cash upgrades within 24 hours of departure, on any type of ticket, will receive the original Virgin Points and tier points according to the original fare, before the upgrade.
