  We examine the capabilities of the DUNE experiment in probing leptonic CP
violation within the framework of theories with generalized CP symmetries
characterized by the texture zeros of the corresponding CP transformation
matrices. We investigate DUNE's potential to probe the two least known
oscillation parameters, the atmospheric mixing angle $\theta_{23}$ and the
Dirac CP-phase $\delta_{\rm CP}$. We fix theory-motivated benchmarks for ($
\sin^2\theta_{23}, \delta_{\rm CP} $) and take them as true values in our
simulations. Assuming 3.5 years of neutrino running plus 3.5 years in the
antineutrino mode, we show that in all cases DUNE can significantly constrain
and in certain cases rule out the generalized CP texture zero patterns.
