I always think Junior Grand Prix scores tend to be upwardly skewed, almost by the nature of the fact that in large fields, there will be a small handful of skaters (or a skater) at the top who stands out. And that fact alone is enough to drive the differential and make for a higher score than people may find "right" in the bigger picture/broader context. This seems especially true in dance, but can happen in singles obviously, and I think the top two ladies in this event warranted the differential step up. Whether they would score these same numbers in a senior event with a stronger field overall, is moot.
