We have seen the new tail design on an Airbus A380 and also a Boeing 787-9, but there haven’t been any hints if this will be a fleet-wide livery update or just a special livery for their new aircraft.

I really like that design, it's very modern. Fingers crossed it actually becomes more than a special (and temporary) livery.
