I don't think it is a YB but, it does show some of the traits I expect just not to the degree I expect(some of which can also be present in normals).
The YB's I've seen have high flames, lots of blushing, a pale head spot and a "gravelly" looking belly edges.
It could be a YB but, personally I wouldn't be comfortable selling it as such unless the sire or dam was an ivory.
If you plan on breeding I would consider her as a wild-type. If she is only a pet, well even wild types are great looking snakes in their own right.
