More than likely, the custom lock on your screen is appearing or disappearing randomly and has nothing to do with KNOX. It probably just changed because you did 'something" to your phone. SysScope is the process that determines the result of the scan to be custom or official. Your phone might stay the way it is now, or it might revert back at some point to custom. Search for sysscope if you want to learn more about it.
