If it is a true scene release there won't be any variants. Unless it was altered with another program like Region Frii, Brick Blocker, ect. But that would be the reason behind the OfflineList, to make sure you have the scene release instead of a rip or just one that someone did and uploaded to a tracker. But if it doesn't matter to you whether or not it is a scene release or not, the list would be useful to you as well, give you a checklist, screenshots, cover. Many uses for the list.
