Ok man your first point is correct, the plane actually seems to have a really minimal turn when banked on a side but I can disagree with your other points.
I haven't a direct experience with jets (sadly) but I play A-10c on DCS and many other aircraft on X-plane 10 that is considered the world's most advanced flight simulator, is certified by FAA and used for pilot virtual training. I can assure you that ALL PLANES make a cospicuous turn when banked.
Moreover I can cite the manual Fundamentals of Flight of the US Army (you can find it on Internet: FM 3-04.203) that says:
7-152. An aircraft, like any moving object, requires a sideward force to make a turn. In a normal turn, this force is supplied by banking the aircraft so lift is exerted inward as well as upward. The force of lift is then separated into two components at right angles to each other. The lift acting upward combined with opposing weight is called the vertical-lift component. The horizontal-lift component (centripetal force) is the lift acting horizontally combined with opposing inertia or centrifugal force (figure 7-42). Therefore, the horizontal-lift component is the sideward force that forces the aircraft from straight flight, causing it to turn. If an aircraft is not banked, no force is present to make the turn unless rudder application causes the aircraft to skid in the turn. Likewise, if an aircraft is banked, it turns unless it is held on a constant heading with the opposite rudder. Proper control technique assumes an aircraft is turned by banking and that in a banking attitude it should be turning.
The last point is fairly conclusive, and is also logical because, as in the wiki image I posted, if a plane fly it has portance, if a I bank it a part of this portance became centrifugal force so, for transitivity rule, if a plane fly it makes turns when banked.
Sorry for my english but I'm Italian ;)
