The Devil and Father Amorth (2017)

Over four decades after he staged a pretend exorcism (and made cinema history as a result), director William Friedkin filmed a "real" one performed by Father Gabriele Amorth, a revered and respected member of the Diocese of Rome. Friedkin presents and narrates his own footage, referencing often the film that made his name, so expect spoilers for The Exorcist (1973).
Prior to the main event there's interview footage of authors William Peter Blatty and Jeffrey Burton Russell. Afterwards the medical community, experts in the fields of neurosurgery and psychiatry, comment on what the viewer has just seen. There's no definitive resolution. Instead, as with the fictional film, a viewer will likely see in the footage their own beliefs reflected back at them, with regards both sides of the incident; i.e. authenticity or artifice.
