If I read this correctly then you're confusing two things, the mode of 
download (HLS, HVF, FLASH) and the quality level (best, hd, vhigh, etc).

To quote from the release notes (2. New default streaming formats):


        "TV

  * HLS (HTTP Live Streaming) is now the default format for on-demand TV
  * HLS downloads are MPEG-TS (transport stream) files, which can be
    played by most media players. The files are re-muxed to MP4 by
    default to make them palatable to AtomicParsley for metadata
    tagging. Downloading with|--raw|will produce MPEG-TS files.
  * RTMP (Flash) format is temporarily still available
    with|--tvmode=flash|. The previous default setting is available
    with|--tvmode=flashbetter|."

And from the Wiki "Modes"


        "Quality levels

Quality level can be one of five possible values (in order of decreasing 
bitrate and resolution):

  * best
  * better
  * good
  * worse
  * worst"


        <https://github.com/get-iplayer/get_iplayer/wiki/release295#radio>"The
        stream type prefixes and quality levels can be combined,
        e.g.|hlsgood|,|hvfbest|,|dashworst|,"


HTH
