Essentially the performed experiment
shows a violation of Bell inequality
(valid for local-realistic models, both
quantum or classical) and a violation
of Leggett inequality (valid for a class
of nonlocal-realistic models). The set
of nonlocal-realistic models (nonlocal
hidden variables) is much larger though.

Dunno. The problem here is 'our reality'.
We have been exposed to the superstition
according to which the quantum world is
afflicted by more uncertainty than the
classical world. Sometimes, or often, this
seems to be wrong. Quantum phenomena
very often are more disciplined than
classical phenomena. In example, quantum
correlations (i.e. entangled pairs at a distance)
are always stronger than classical correlations
(i.e. two fragments of a bomb).
Perhaps there is just a smooth transition
from our 'reality' (whatever it means) to
another 'reality', and so on.
