If she was sold to you as a hypo, then that's probably what she is. Remember that there is a ton of variance between different examples of the same morph. I have a hypo het lavender stripe girl who has VERY similar markings. Strawberry isn't that common for it to be widely spread in the gene pool yet.
That being said, it is possible that it cold be a strawberry, I had a "ghost" corn turn out to be an ultra anery even though it was purchased before ultra was even really around. But it's unlikely.
Regardless she's a good looking snake for sure! I'd test her against an amber or something if you wanted to know what type of hypo she was.
