She's definitely got an interesting belly! Love that stripe on her back too. I wonder if she's actually a het pied with some of the pied markers bleeding through a bit differently. Is there a picture of her sides? Is there any flaming or heavy blushing down by the belly?
If she was in my possession, I'd try breeding her to a pied and see what I get. All pieds is most likely a very interesting super low white mom. Mix of het pieds and pieds would mean she's a het...unless the babies also hatch out with her very interesting pattern.
To me.... even her color seems a bit off for a Pied. A lot of them have more of a high gold coloration and she looks pretty dark.
Hopefully someone with more experience on extremely low white pieds can pop in with an opinion... but I really do love the look of this girl.
Also....
2 of these do look similar to yours, so maybe they're from a similar line
