Will we ever get optics with more accurate in game portrayals? i.e. Only the optic zooming and not the entire FOV?

As the title asks. Also, when looking through an ACOG, you don't see all the details of the optics structure. Just a sharp black circle circled by a thin blurry outline of the frame. Not my reticle in the first picture, but you get the idea. How do I know this? Second picture is my rifle: http://imgur.com/a/n6uKZ
