Is the P.T demo playable?

So, I might have acquired a copy of the P.T demo and installed this to my PS4 (5.05).

I can't figure out how to get it running though. I don't even know if it can be ran. The lock will not disappear, and I am unable to launch the game. All other games seem to work fine.

I think (hope), I managed to download a fpkg version of the game.
