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.
