Yes, most if not all of the professional observatories use a form of point modeling software. T-Point is quite common. Professional telescopes with mechanical fault tolerances kept to a minimum through advanced engineering and manufacturing processes still exhibit point issues. Software modeling simply compensates for these mechanical errors. Hence benefits can be experienced from both professional and amateur astronomers.
Most of these telescopes operate at such long focal lengths which result in a narrow field of view. This makes it difficult to ensure objects are centered on a CCD detector every time the telescope is slewed to a different object. This task would be almost impossible without some form of modeling.
