Anybody knows if "BDAV" format listed below refers to BDAV disc format 
(vs BDMV) or to the m2ts transport stream format?

Yes, possibly better. I will think about it.

Dolby Vision isn't mentioned in the specification? I verified that my 
own DV25 file also has "Overall bit rate of 28.8 Mb/s. Here are the most 
DV mentioned lines from the Whitepaper:

  * Direct recording of DV contents from the DV terminal of the
    camcorder with no picture deterioration (option)
  * Taking advantage of the BD-RE drive’s high user transfer rate
    (36Mbps), the BD-RE Application Format provides an optional
    functionality of recording DV streams (28.8Mbps) to BD-RE disc via
    the i.LINK.

  * Direct Recording of DV Input. The recording format for the DV stream
    conforms to the DVCR digital interface standard (IEC 61883-2) (Fig. The DV stream received through i.LINK is not re-encoded
    but recorded directly to disc, with aligning the beginning of the DV
    stream with the logical sector boundary, as shown in Fig.

  * Figure Data structure of DV stream (compliant with
    digital interface standard for DVCR)(525 / 60) (626 / 50)
  * Fig. shows the directory and file structures. DV stream
    files are stored in the /BDAV/STREAM directory as are TS files. DV
    stream files have the extension “dvsd” and are accordingly
    distinguished from TS files.

  * Since the video compression method adopted by the DV format is
    intraframe coding, each frame in the DV stream has a fixed number of
    bytes (525/60:120,000byte, 625/50:144,000byte).

  * DV stream has a comparatively high transfer rate of 28.8Mbps,

  * As previously described, the BD-RE Application Format adopts MPEG2
    and DV formats as its video recording format (recording codec). When
    MPEG2 is used for recording, each frame image of the content is
    coded into either of three types—I-picture, P-picture, or
    B-picture—and compressed and recorded.
