The loophole-free quantum experiments of Vienna, NIST and Delft last year do test rigorously for local realism and they show that it can't be true. The conclusion is indeed that we have to abandon the hypothesis of local realism.
How can that be? You said yourself, "In real Bell-CHSH experiments, we can't observe quadruples (A, A', B, B')." If you can't observe that quadruple then you can't test for local-realism in a quantum Bell-CHSH test experiment. It is just not possible.
