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.
