Nvidia proprietary driver returns the requested version. It's allowed by the
spec:

    If version 3.2 or greater is requested, the context returned may
    implement any of the following versions:

      * The requested profile of the requested version.
      * The requested profile of any later version, so long as no
        features have been removed from that later version and profile.
