Example:

When you frame the picture between the long edges (like OP) there is a noticable difference in background blur depending on what aspect ratio you use.

The images are cropped, so we can't se how they were framed. What matters here is that the shooting distance is held constant. If it is, then the vertical and horizontal FoV will vary with the cameras native aspect ratio, but the diagonal FoV should be the same.
