If I understand correctly, in an aircraft, zoomed all the way in, you are seeing a 1 to 1 image. In this position, due to it being on a 2-D computer screen, you lack the peripheral view.
So, when you are not zoomed in, the view you see is compensating for being on a computer screen.
In a vehicle, what you see is what you would actually see looking through the particular sight. There is no peripheral vision loss to compensate for.
