Comment (by Cigaes):

 I suspect you confuse '''sample''' aspect ratio and '''display''' aspect
 ratio.

 {{{ffprobe}}} shows 0/1 for the '''sample''' aspect ratio, meaning it is
 not explicitly defined in the stream. Players usually treat it as 1.

 Your video has resolution 1920×816; assuming the '''sample''' aspect ratio
 is 1, that makes the '''display''' aspect ratio approximatively 2.35,
 which is a very standard aspect ratio for cinema movies. There is no 16/9
 here, except probably for the initial content that was later cropped.
