  For $G$ a Polish group, we consider $G$-flows which either contain a comeager
orbit or have all orbits meager. We single out a class of flows, the maximally
highly proximal (MHP) flows, for which this analysis is particularly nice. In
the former case, we provide a complete structure theorem for flows containing
comeager orbits, generalizing theorems of Melleray-Nguyen Van Th\'e-Tsankov and
Ben Yaacov-Melleray-Tsankov. In the latter, we show that any minimal MHP flow
with all orbits meager has a metrizable factor with all orbits meager, thus
"reflecting" complicated dynamical behavior to metrizable flows. We then apply
this to obtain a structure theorem for Polish groups whose universal minimal
flow is distal.
