I fly the same heavy commercial jets (and previously, things with much higher wing loading again), and contend that the effect can’t be seen, because it doesnt exist.. When you’re flying a holding pattern up in a jetstream, what happens to your IAS - a.) alternating stall and overspeed warnings, or b.) nothing ?
c) Same thing which happens holding in still air, which is that the IAS bleeds off during the turn then increases during the leg, then bleeds off during the turn. lather, rinse repeat. In my airplane (> 100,000 lb, not equipped with autothrottles) this is easily noticeable.
