I take back what I said above
It doesn't seem like platinum gets you anything really, the new lounge is
nothing special and as a Plat you can no longer use your points without taking to a host first,
and when you upgrade to Plat it no longer shows your points on the website
A friend asked to downgrade to Gold so he could use his points, they said no.
Their marketing seems aimed at the bottle service crowd that doesn't gamble.
