Has a FIBA World Cup game ever ended 95-91?
Exactly once. On August 15, 1990, Australia beat Argentina 95-91, and no FIBA World Cup game before or since has ended that way. When it happened it was a scorigami, the first 95-91 in league history.
That makes 95-91 the 240th most common final score out of 863 that have ever occurred in FIBA World Cup. One point away, 96-91 has happened never and 95-92 has happened never.
