Maybe those files are not cataloged by RMAN? I would CATALOG them and then DELETE OBSOLETE once again.

You should be able to backup an 11.2.0.2 database using RMAN with an RMAN repository that is set to 11.2.0.4. There seems to be some invalid objects in your RMAN repository schema. You may want to try compiling all of the invalid objects in your RMAN repository to see if they become valid. This probably has nothing to do with you backing up an 11.2.0.2 ...

There are no architecture differences in RMAN itself. The difference is in the speed of the backups if written to the Exadata on-board storage. So the advantages that Exadata brings in terms of hardware would also translate to advantages in backup speed and MTR (mean time to recovery). But none of those advantages are the result of changes to RMAN.
