Various structures are visible within Spectro-Polarimetric High-contrastExoplanet REsearch instrument (SPHERE) images that are not alwaysstraightforward to interpret. In this article we present a review of thesefeatures and demonstrate their origin using simulations. We also identify whichexpected or unexpected features are limiting the contrast reached by theinstrument and how they may be tackled. This vision paves the way to designinga future upgrade of the SPHERE instrument and the next generation ofhigh-contrast instruments such as those planned for the Extremely LargeTelescope (ELT).
