I think that if you paid for the upgrade and are unhappy, you can probably ask to cancel that upgrade and get the fee refunded. You may also be able to change your flight to a date that would have the lounge operational if you want.

If not, AF may give you some a few miles for compensation or onboard duty free voucher (in both cases they'll likely do that automatically if that's the policy) as a gesture of good will but hardly more than that.
