What makes you so sure that the Night Pride are Barbary Lions? For one thing Barbary Lions are not a seperate subspecies and for another they are extinct in the wild. So it is extremely unlikely that the Night Pride are Barbary Lions also they are far too dark in color to be Barbary Lions.
Because we can't know for certain which species were used in the show. There are a number of different subspecies in the franchise and we can't be sure which ones were used and which weren't. Some have various geographical distributions that help identify them. In the franchise the geography is very different from the real world so that doesn't help. Plus this is a wiki not an encyclopedia.
