It would depend on where Heve60 got upgraded. If it was at the gate then there would have been no CH experience, just the cabin.
Both times we didn't get told of the upgrade until we reached the boarding gate, so yes missed out on all the perks. However when travelling to California last year we paid to travel UC, so was entitled to limo, clubhouses, UC cabin etc.
IMHO, the PE product to Orlando on VS is perfectly ok and I would certainly have to think long and hard before parting with my hard earned cash just to upgrade to UC especially when you already have the comfort of PE.
