Nope. You are confined to the gate area. No lounge. My wfie did this flight last month (in F) and this is how it worked (and it how it worked when I last did the flight in 2003).
Customs clearance (for both pax originating in HKG and those originating in YVR) is at JFK, just like any other international arrival (Ireland and Canada excepted).
