That's not entirely that simple: the main allowance based on cabin/flight is that of the main segment (in this case the transatlantic) but AFAIK status-related benefits do not apply to code share flights. In this case, the outbound will be no issue as you'll check everything through from DUS, but I am not so sure about the return.
