In store screen saver

I Just got my wife a new iPhone 6s Plus. I noticed that in the store, most of the "i" devices had a screen saver that displayed while in sleep mode. It's this hi-def, high color Swirly graphic that played for a few seconds every minute or so. I even noticed a still of this same graphic displayed somewhere on apples website and even in a few commercials. I am wondering if that is a special store only display mode it's in or can that be turned on at home and how?
