I did all the hard work so you don't have to. Check out my comparisons below.

By the way, it takes the iPhone 7 and 7 Plus 6 frames longer to finish the animation than the iPhone 6. This is because the wallpaper lags behind.
The iPhone 6 transition is steady and smooth the whole way through, whereas the iPhone 7 and 7 Plus both hiccup halfway through the animation AND the wallpaper is static for the first half of the animation (which is also a bug).
