Ps4 game disc and download?

I'm just wondering what happens to the installed game and my score on a ps4 when I get the license for it via ps + and the disc that I played with before was only borrowed from someone. Then I could give the disc back and continue playing with the license or would my game status be deleted? And what happens to the installed game itself? Usually you will be asked for a disc if one is not inserted. Does my PlayStation automatically know that I now have a license or do I have to uninstall and reload the game first?

Even if you uninstall the game, your game save will not be deleted. Your score has nothing to do with the application itself.
