Lollipop boot animation

I may be in the minority but I like the original Kitkat boot animation that carried on to Lollipop 5.01. Also I would like to keep that original boot screen and animation in case something goes wrong and I need to return the phone on the extended warranty I have. Now when I load the custom rooms, I get another boot logo and animation, a new M and colored dots running about the screen instead of the world thing that normally animates. How can I extract the animation sequence and either flash it back with TWRP or manually change it in my phone. Thanks.
