The Kardar-Parisi-Zhang (KPZ) class is a paradigmatic example of universalityin nonequilibrium phenomena, but clear experimental evidences of asymptotic2D-KPZ statistics are still very rare, and far less understanding stems fromits short-time behavior. We tackle such issues by analyzing surfacefluctuations of CdTe films deposited on polymeric substrates, based on a hugespatio-temporal surface sampling acquired through atomic force microscopy. A\textit{pseudo}-steady state (where average surface roughness and spatialcorrelations stay constant in time) is observed at initial times, persisting upto deposition of $\sim 10^{4}$ monolayers. This state results from a finebalance between roughening and smoothening, as supported by a phenomenologicalgrowth model. KPZ statistics arises at long times, thoroughly verified byuniversal exponents, spatial covariance and several distributions. Recenttheoretical generalizations of the Family-Vicsek scaling and the emergence oflog-normal distributions during interface growth are experimentally confirmed.These results confirm that high vacuum vapor deposition of CdTe constitutes agenuine 2D-KPZ system, and expand our knowledge about possiblesubstrate-induced short-time behaviors.
