I don't think that's quite it. If you've ever used a projector on a
whiteboard that isn't intended for that purpose, you see the reflection
of the projector's bulb/lens on the makeshift screen. I think a gloss
surface is too reflective, semi-gloss might be ok.
This would also be pretty sensitive to how it is applied. With a normal
roller or brush you get a texture that would not be ideal for a screen.
However, the OP didn't indicate that this is the actual application
here, so we might be making a bad assumption.
