is this normal for a Normal?

I searched "het piebald belly markers" and the last thread was 2015. So, I'm posting this as a fresh question. I'm actually hoping that she isn't het for anything, looking for a blank slate. I got her last week. She was somebody's pet. I like the dark Normals, the price was right, and she'll be ready to go this season. When I asked what morph she was I was told "Ball Python" so yeah, they're clueless.

There might be something genetic going on with the side pattern. Belly looks pretty normal to me. Pied markers are usually on the underside and sides of the tail. The white pied markers are more triangular than what I'm seeing on this one but I'm not sure what part I'm even seeing because I don't see the tip of the tail. There are some questionable parts on the belly that look similar to Pied markers but some normals just have those and I'd put more weight into how it looks closer to the tail.

Here's a tail shot:

Nope, no pied markers.
