Doesn't look like the type of dial which would have onyx inserts - the indices don't show any gaps where the onyx batons would sit in. In regard to a redial, it's kind of hard to tell if that is the case because this picture is pretty low-resolution. Clearer pictures will be needed if you want people to verify the dial for you.
Onyx markers will not have lume - instead the hands will have a black strip where the luminous compound is placed on this one. Looks good
As above this one is fine. Lumed hands and recesses for lume on indices. For clarity, watches with onyx indices can have lume - but as dots outside the markers not in recesses (as I was embarrassingly reminded once - even though I have one )
