I personally like the image grain - adds a very organic feel to an otherwise antiseptic (though beautiful) environment. My only concern would be the potential performance hit it would take to paint the grains during render time.
It really isn't very expensive performance-wise. The image grain is simply a transparent texture than pans and rotates (to give the illusion of the grain moving as it would on a screen), scaled up or down depending on the screen resolution, and rendered over the scene. A very cheap post-process effect. If you ever play Batman: Arkham City (which uses the same game engine) on PC, you will see the image grain effect is there as well, and you probably didn't even notice it was there in the first place.
