I don't know about the island upgrades, but they reimbursed gems when they changed the silver and gold shrines to be purely decorative. Those of us who had gotten gold shrines the old-fashioned way (either by leveling dragons or spending gems) got a ton of gems for each one. They might do something similar with this.
