The Pusey-Barrett-Rudolph (PBR) theorem and Einstein proof for incompleteness of Quantum Mechanics

In 1935, after the publication of the EPR paper, Einstein gave an argument for the incompleteness of Quantum Mechanics, i.e. he showed that the wave function cannot provide a complete description of the physical state of the system. His argument, in the same setting of the gedankenexperiment of the EPR paper, is the following:

consider a joint system $(AB)$ to be prepared in an entangled state by some ‘collision’ between the subsystems $A$ and $B$; a choice of measurement on $A$ can result in the subsystem $B$ being described by one of two quantum states $\psi_B$ or $\phi_B$.

Now what is essential is exclusively that $\psi_B$ and $\phi_B$ are in general different from one another. Einstein asserts that this difference is incompatible with the hypoth- esis that the description is correlated one-to-one with the physical reality (the real state). After the collision, the real state of $(AB)$ consists precisely of the real state of $A$ and the real state of $B$, which two states have nothing to do with one another. The real state of $B$ thus cannot depend upon the kind of measurement we carry out on $A$. (‘Separation hypothesis’ from above.) But then for the same state of $B$ there are two (in general arbitrarily many) equally justified $\psi_B$, which contradicts the hypothesis of a one-to-one or complete description of the real states.

What Einstein does with this argument is actually something more than simply denying $\psi-completeness$: under the separation hypothesis (which is actually a consequence of the principle of locality, due to the space-like separation of $A$ and $B$), he shows that the same real physical state of $B$ is compatible with two (in general, even infinitely many) different quantum states $\psi_B$ and $\phi_B$. Thus, Einstein establishes the failure of $\psi-$onticity! According to Einstein, an ontic aspect of the wave function would entail a contradiction with locality.

On the other hand, in the year 2011, Pusey, Barrett and Rudolph (PBR) showed that the wave function must have an ontic aspect; otherwise, a $\psi-$epistemic approach would entail a contradiction with the quantum recipe.

My question (maybe stupid) is: we should then conclude that Einstein was wrong and actually Quantum Mechanics has some non local aspects?
