S7 Edge Always on Display Screen Burn in??

[The Slayer]

Hey,
So i recently bought a S7 Edge and i have always on display on , cuz it looks sick but i want to know if it leave burn in marks, Some say that it moves every once in a while but i haven't really noticed that , i didnt look at it for long , if it does move does anyone know how often ??
If you have used the s7 edge for a while with AOD enabled does it leave burn in marks, oh btw the AOD moves every time i unlock the phone and lock it.

Turn off the display when you're not using it.

There no practical reason to have it on, plus your battery will be gone within 3 hours if you leave the display running.
