The DME does an outstanding job of monitoring and adjusting AFR by bank - it has no ability to see or understand AFR by cylinder. I'm not sure as to whether Cyl. 5 runs a touch lean, bank 2 has never shown consistently leaner conditions but the DME's behavior would be to simply richen up Cyls. 4 and 6 in the event that 5 went lean. So far as it's concerned all is well, even though Cyl. 5 is not happy the bank is hitting lambda.
That's speculation on my part, to be clear.
If you are only seeing corrections on Cyl. 5 and global timing looks good, you are probably just fine. A log with 0 corrections at any point across any cylinder is tough to pull off on the street.
