If the stateroom is on Deck 6, lifeboats will be visible as you look out on your veranda. You won't have a clear view of the sea. If you are on Deck 7 and above, you can look directly out at the sea, but if you look down from the rail of your balcony, you will see lifeboats and not see directly down at the sea. This case it is not considered an partial or obstructed view balcony.
On the S-Class (with the exception of Reflection), there is a window washing contraption obstructing your view out. This is on the Deck 11, staterooms 1547/1549 on the port side, and 1552/1554 on the starboard side.
What stateroom are you looking at?
