The most high end card in most bank normally come with 2 path to apply, one is AUM with the bank, another is superb high spending individual.
As like diamanté card, you are right, private wealth customer with AUM 1mil USD will automatically get the card even he/she do not spend a single cent with any Maybank credit card before.
Another way is superb high spending individual, in this case, 600k annual spending is the criteria for this diamanté card even you do not qualify for the AUM part.
This is the same for the UOB RESERVE card, 2 mil SGD AUM or SGD 250k annual spending to qualify for the card.
Back to the diamanté card, status is not one of the benefit for this card as Maybank is not well known at most others country. The good point for this card is the 5X TP for local spending, and because this is a VISA card, is much wide acceptable than AMEX.
i have exceeded 600k spent for the past 12 months... let me try if they allow me to do so
