Under 1GB, wow that's small...
Dune doesn't appear for me as a Prime title, but I do happen to have it on Amazon (sync'd through my Movies Anywhere account) and for the heck of it I thought I'd download it to my cheap 2015 Fire 7 since it's sitting here next to me. The file on that is reported by the Fire as being 1,006 MB (on a non-HD device) when downloaded at "Best" quality.
