Simulations show current GRAVITY data cannot distinguish exotic compact object models from black holes for Sgr A* flares, but GRAVITY+ sensitivity may allow detection of some models unless the hot spot is modeled with greater astrophysical complexity.

Sagittarius A* near-infrared flares polarization as a probe of space-time I: Non-rotating exotic compact objects
