  Oscillation studies play a central role in elucidating at least some aspects
of the flavor problem. Here we examine the status of the predictions of a
lepton quarticity flavor theory of neutrino oscillations against the existing
global sample of oscillation data. By performing quantitative simulations we
also determine the potential of the upcoming DUNE experiment in narrowing down
the currently ill-measured oscillation parameters $\theta_{23}$ and
$\delta_{\text{CP}}$. We present the expected improved sensitivity on these
parameters for different assumptions.
