Which means there is no possible way that the small file can contain every junction view present in the large file. <...>.

Just to look at things from a different perspective... is the 51 MB JCV file so much smaller than the 446 MB file because it contains less images of junctions? Or could it be the file size is smaller because the images have a lower resolution...??

The same route with the smaller file had zero.

The smaller file has fewer images.

Your effort to try this out is much appreciated! I wonder on what basis Garmin has selected these fewer images.
