I am honestly not sure about going back, but I have had no problems. In fact, when I booted after root, something (sorry I dont remember if it was during root, or after) asked me if I wanted to disable Knox. I said yes, and smooth sailing ever since. I think it might have been the super user app itself that disabled it for me.
