Does VRRP replace the IP addr on the backup device?

When failover occurs:

Does VRRP replace the IP address on the backup device? Or is it an additional IP address?

I don't think that any of the gateway redundancy protocols replace the actual IP address on the primary or backup devices. The actually physical interface addresses are distinct from the additional address (virtual IP address) which the device hears on if it is the master router.
