UDF is told to have replaced ISO for optical CD/DVD/BD discs.

I wonder if someone can clarify if UDF version 2.5 or higher really is
required for creating and burning Blu-ray video to VBD-discs.
I've got this impression earlier, i.e for K3b here, which still seems
to be much the case on Linux:
https://bugs.kde.org/show_bug.cgi?id=257602
I've seen there could be UDF 2.5 on Ubuntu and possibly with tsMuxer(?)
Bt in my case on Leap 15.4, and even on Tumbleweed, the latest
available udf package versions are 2.1 and 2.3:
S | Name | Type | Version | Arch | Repository
---+----------+-------+-----------------+--------+----------------
i+ | libudf0 | pakke | 2.1.0-1.27 | x86_64 | Main Repository
i+ | udftools | pakke | 2.3-lp154.321.3 | x86_64 | 15.4
udftools 2.3 is even an experimental package from OBS with content
/usr/bin/udfinfo
/usr/bin/wrudf
/usr/lib/udev/rules.d/80-pktsetup.rules
/usr/sbin/mkfs.udf
/usr/sbin/mkudffs
/usr/sbin/pktcdvd-check
/usr/sbin/pktsetup
/usr/sbin/udflabel
So what happends and decide the udf file system version when using
mkudffs, bdwrite and dd or K3b lastly for burning?
when I let K3b autodect the image (because there are no selection for
UDF), it actually shows "ISO 9660" while burning.
And the result has prooved to be playable Blu-ray discs in hw player.
First, to correct one possibly confusing typo above: VBD-discs should be
Blu-ray video discs
To add An extract from udfinfo for one of my burned BD-RE dscs:
udfinfo /dev/sr0 | grep udf
udfinfo: Warning: Device '/dev/sr0' is busy, udfinfo may report bogus
information
udfinfo: Warning: Second and third Anchor Volume Descriptor Pointer not
found
udfinfo: Warning: Logical Volume is in inconsistent state

udfrev=2.01
udfwriterev=2.01
