We had another one night stay here in late July, with Platinum status.
I had booked the cheapest "Classic Queen" room and we were upgraded to what I always assume to be a "Luxury" room at the lounge end of the hotel. (The hotel's room descriptions aren't entirely transparent, but a second armchair and a capsule espresso machine are what I believe distinguish "Luxury" from "Superior".)
Proper in-room coffee is actually the thing we most appreciate when we get upgraded here, so this was a success.
