Depolarizing channels suppress the correlations needed to witness both state-dependent and state-independent contextuality in sequential KCBS and Peres-Mermin implementations, leading to classicalization.
Kochen-Specker contextuality generalizes nonclassicality while Spekkens' noncontextuality generalizes classicality, reconciling the two as successive stages in a hierarchy of classicality.
