Thanks for the update.

Is the D4XX format on these devices the same that's documented in
Documentation/userspace-api/media/v4l/pixfmt-meta-d4xx.rst ? I.e. there are
no additional fields or differences, and the version of the format is the
same?

The format documentation doesn't say which version number even the current
devices use (just refers to "xxx").
