I am using Kodi on Nvidia Shields to stream movies. Some of them are in
.iso format. One Nvidia unit I have connected to my NAS via my Lan network.
My movie files in .iso work fine there.
The same movie files copied to a USB drive plugged in to another Nvidia Shield
will not recognize the .iso files, although it sees other movie files (MKV, etc) OK.
Both Kodi aps and Nvidia Shield  units have the same versions of firmware.

Look in addons , i think you need to have a iso addon from virtual file system

I think that's an Android problem, for Kodi to access local files special permissions are required from Android for media files, and Google doesn't class iso files as media.
