The picture is clearly "international meal service", so if it is pictured on a "domestic flight", then it would be a transcontinental PER flight.Presume you were on an A330?
So what we are talking about here (as pictured) is "international meal" not "domestic meal" (as Qantas markets "international meal service" on those PER routes). If you fly J on a B737 QF transcontinental PER service you get the same "international meal service", but if you fly J on an A330 domestic service that is not transcontinental, then you receive the standard J tray service (not the plates by size service).
