We used to be able to detect YouTube Safety Mode via an App-ID, but due to recent changes in Google's implementation, this no longer works. As such, you must rely on the PAN-OS 6.0 Safe Search Enforcement feature to enforce YouTube Safety Mode in your environment.
As mentioned above, YouTube Safety Mode is included as part of the SafeSearch Enforcement feature in PAN-OS 6.0, provided that you've updated your content to version 422 or later. If you've done this and are not seeing support for YouTube Safety Mode, please open a case with Support.
Just a thought, but when I surf to http://youtube.com (or any other google service for that matter), I am redirected to https (SSL). Decryption will be needed in order to apply safe search restrictions
