My theory is, that at the check-in on that day a group of HONs showed up together and went on a happy trip to South Africa taking away all the upgrade availability

So honestly, it seems to be very hard / impossible to get F award upgrades on A 380 unless you are a HON, SEN is not enough...
Good Luck in trying!
I have used 2 evouchers recently to upgrade from D to F on FRA-NRT. Was waitlisted for quite a while but 3 days before departure all cleared.
And yes, as far as I have been told A380 F as award or upgrade is SEN/HON-only.
However I wouldn't say it is hard to get.
