That appears to be the same knockoff that has been proven to be fake in another video. The other one was black though.
Here's the video:

Notice how both have the metal ring (external antenna) color matched with the color of the phone (unlike what we have seen in leaks, where the color was either gray or graphite), while the +, - and sleep buttons are silver whereas they should be the color of the ring.
Both are seen in a low-quality YouTube video in which the phone doesn't move during the animation, so it would have been easy to just edit the movie and add a video on the screen.
The other (fake) leak was later said to be a dummy gotten from that chinese website:
http://item.taobao.com/item.htm?spm=a230r.1.10.1&id=19623600390
I can't confirm if was actually gotten from this site, but in the other video it's a lot more obvious that the booting animation is fake and just a video pasted on top.
This one appears to be the same one as in the other video, except in white.
