Client log doesn't detect QoS
When QoS is enabled via GPO, the log when viewed with Snooper shows qosEnabled as false, but a wireshark trace shows the DSCP on the packet as 46. Wireshark: Snooper:
You'll se a difference because the Policybased QoS policy adds the CoS information to the IP header, which happens at layer 3 (network layer), your Snooper looks at layer 7 (application layer) and has no idea, what so ever, to whats happening at the other layers.
If you were using SFB server, the Set-CsMediaConfiguration should set this (as Michael LaMontagne correctly points out), however that is not available for SFBO, and is neither applicable for Windows devices, who gets the setting from a GPO.
