I noticed that no clients were connected to 5GHz on the one Unleashed site I have running 200.16 firmware and R650 APs. I got on site and used my spectrum analyzer software to confirm that it was not broadcasting anything in 5GHz. I set up a test 5GHz only network as well with no results. I saw on forums that people had had that issue with other firmware versions in the past, but nothing mentioned for 200.16. I decided to downgrade to see if it would fix it. In the upgrade section of the Unleashed web interface there was an option given to downgrade to a previous firmware, so I just did that instead of finding and uploading a specific firmware version. It downgraded me to 200.15.6.112.54, and 5GHz was working after that. So, not sure if this is a problem multiple people are having or not, but it would be great to see a fix in the next version of Unleashed.
