The 2nd stage nozzle looked a bit different on this one.. not sure if it is a different angle of the camera or what..
The second stage nozzle is a short one that was last used on the Transporter 7 mission. It is used to save money and when less "energetic" missions are needed. So this was not a mission that was pushing the limits of the rocket, so a smaller, less efficient, nozzle can be used.
