Room Capability Notation

What is the PrivaSea room notation? This was taken from Bliss Deck Plan.

PrivaSea is NCL's room type name for an enclosed balcony. Enclosed balcony staterooms that are located towards the front or back of the ship have balcony staterooms where the metal hull of the ship forms an enclosure for the balcony. You will still be able to sit outside in the balcony. The advantage is that you have a little more privacy in the balcony compared to a regular balcony stateroom.

Looking at images of Bliss I don't see any cabins that would qualify.

I think the deck key is just the generic image for all of NCL’s ships. I don’t think the Bliss has any Privasea balconies but if they do there are very few. I didn’t see any on the Bliss when I did a very quick check of the deck plans.
