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
* Direct Recording of DV Input. The recording format for the DV stream
conforms to the DVCR digital interface standard (IEC 61883-2) (Fig.
188.8.131.52.1). 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. 184.108.40.206.2(a).
* Figure 220.127.116.11.1: Data structure of DV stream (compliant with
digital interface standard for DVCR)(525 / 60) (626 / 50)
* Fig. 18.104.22.168.3 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.
