I would say these are all bugs, they show the driver not correcting the
value and allowing users to read back out of range values that were
written.  Even if the driver is accepting out of range values I'd expect
it to transform them somehow when storing, the program will accept a
mismatched read when testing this case but it will complain if the read
value is not valid according to the control's info.
