Sadly for you, the A380-800 that you'll be on doesn't have Y seats on the upper deck.
Can't say there is much that is unique to see on the A380 but you will have a comfortable ride. The humidity and pressure are more favorable for the flight which can help reduce travel fatigue.
EK also have a features on your flight section of their website. It shows amenities for the flight you'll be taking.
