They missed adding this line,
HKR,, Catalyst_Version,,"10.1"
to the [ati2mtag_SoftwareDeviceSettings] section in the INF. Probably missed because the CCC hasn't been updated in a release or two. You can add it manually if you and run the install again if you want to see it say 10.1, but it will break the WHQL in doing so (get the red warning about non-WHQL).
