Absolutely you would. The top of the hull isn't much more than a meter or two below the edge of that window and extends a completely flat surface at least 80 meters aft.If you were a 6-foot something Riker looking down right out the window, yes...you'd see the saucer before you. However the camera never had that vantage. Looking flat out the window you wouldn't have seen anything.
The only camera angle that wouldn't show the top of the hull through those windows ALSO wouldn't show the floor of the observation lounge. To not be able to see the saucer from those windows would be like not being able to see the street from your first story window.
