Question about the PS4 background?

I set my own picture as a Playstation background but after a while if you don't do anything, the picture turns off and it's just a blue background. Can you turn that off?

No, I don't think so, because the screen saver is there and you can't set a picture

No, this is the screen saver that is activated after inactivity

No, unfortunately this can't be turned off, this is a screen saver that is activated when inactive. If you do something on the Ps4 again, the picture comes back.
