It used to be that if I played the same piece of music every day for a couple weeks, I could remember the sheet music itself well enough to read it when it wasn't actually there. I also had muscle memory, but I was "reading music" as opposed to performing memorized music. This served me well when someone hid my book after a couple weeks on the gig. I just looked at the next guy over's to make sure I was in the right place, and played off the pictures in my mind. Alas, that has slipped to a degree as I have rarely faced such a challenge in real world gigs. Either the set list doesn't change, or there's a place to put the music.
Now I'd say it's about a 3/5. Red apple? Check. I can see the hand holding up the apple, and the shine from reflecting light from a (real) lamp, but it's very faint and transparent as if it were an illusion spell I successfully identified and disbelieved. I can move my head around and my imaginary apple "holds still" correctly. To a limited extent, I can rotate the apple in 3-D space.
