Now those would be useful to back-up, because the on eMMC copy is the only copy there is.

But the question (and my reply) was about what appears as /mnt/us internally - the OP had reported that attempts to copy that where coming up blank.

The file system area used by the USB storage (which is FAT32) could, but does not, have anything stored between the start of mmcblk0p4 and the start of the file system. (*)
(FAT32 has provisions for such things, but in this case they are not used by Amazon, the start of the file system is aligned with the start of the partition.)

If someone is curious enough, they can dig back a several of years in this forum and find a discussion between Geekmaster and myself about using that area for JB purposes.
The decision was: Nope, would not help any.
True -- mostly. At least some stuff is there:
/var/local/cc.db has the Content Catalog, with all your books, and more importantly collections.
WiFi passwords are stored in /var/local/system/wifid.conf -- although it is encrypted.
