Once the Storage Domain is attached all the ovf data from the OVF_STORE disk is being copied to a DB table called "unregistered_ovf_of_entities".
This table is being used to determine the VM configuration once you register(import) a VM to the setup.
You probably still saw VGA after changing the OVF file since the data in this table has not been changed.
