@jorgearq, in this particular scene the inaccuracy of reflections is caused by the limitation of light probes irrespective of their type (cubic or spherical). To produce realistic reflections of objects at different distances (eg. a standing person in the foreground, and a wall in the background) full 3D information is necessary. However, images captured by light probes are like panoramas - they cover all the surrounding but they are only 2D - so they do not produce enough information for fully realistic reflections.
This is true for light probes in general, so a similar scene in Twinmotion will suffer from similar inaccuracies and distortions of light probe based reflections.
