It would pretty much just be a quality of life thing, not having to start the video, wait for the first audio, and then realise it is not available in the original language. Could also just check in the Amazon app on the phone before I start a video, so not an insurmountable problem, just a nice to have.

I have obviously no idea how Kodi functions internally, so im taking your word for it. Thanks for the response though!
