What are the benefits that a platinum supplemental card can duplicate with the primary card holder?

My understanding in the table (will edit the post based on feedback)

	Priority Pass	yes (+1 card only)
	Plaza Premium / DL / VA / LH lounges	yes (LH no)
	American Express hotels	yes (if through travel portal)
	Accor Plus	no
	Hilton / Marriot / Radisson status	yes
	Avis / Hertz status	yes
	Luxury rail	yes (if through travel portal)
	Cruise benefit	yes (if through travel portal)

Looks good. Note that you get access to priority pass for the primary account holder and one supplementray cardholder not for each supplementary cardholder.

Lufthansa Lounges. Primary card holder only.

Priority Pass is only available to one supp card.

All supp cards do get hotel status (Marriott, Hilton and Radisson) as well as car rental status.

How does this work? I am not aware of an obvious marking on the card that indicates it's a supp.

Neither am I.
I am confident it will work the same as VA lounge access

I remember somewhere the format of card number can tell if it a supp, or simply the machine used to validate the card can tell.

VA doesn’t have this capability luckily.

It's always good to try anyway why not

American Express Centurion lounges: pretty sure that supp cardholders have access.

Leaving aside its practical enforceability, is the rule about primary only on Lufthansa lounges published anywhere? I don't recall having seen it mentioned in the places where I learned about Lufthansa lounge access being a Platinum benefit in general. I've just done a quick scan of the T&C at the US Amex website, and it seems to exclude attached Gold/Green cards on a Platinum account, but not Platinum supps.

That is correct. They have access to all lounges on the amex app that doesn't require a PP
