The movie was originally given an X rating by the Motion Picture Association of America (MPAA) in 1987 due to its graphic violence, in sharp contrast to most other X-rated movies that received the rating due to strong sexual content. To appease the requirements of the ratings board, Verhoeven reduced the blood and gore in the most violent scenes in the movie.
So I spot checked some of the scenes in Prime's video and this looks like the X-rated version according to this comparison: https://www.movie-censorship.com/report.php?ID=3609994
It also has the correct running time of 103 minutes. There is more blood and gore in this version. The Amazon page does not specify if this was the X-rated version though, so I checked it myself out of curiosity.
