>Since level should be written as decimal, 50 here is correct for UHD
content with level 5.0 and generated mpd states codecs="vp09.00.50.08"
which is also correct.
The above is an hex dump, not decimal. 0x50 being visible in an hex dump
of the vpcC contents means it's wrong.
Since the values in the vpcC box are decimal, as defined in
https://www.webmproject.org/vp9/mp4/#vp-codec-configuration-box, level 5
needs to be written as 50 (0x32) and not 0x50 (80).
The dash muxer was adapted to interpret them as decimal as well, and
that's why the output is still codecs="vp09.00.50.08".
