It depends who the breeder was.
99% of same strain seed will produce different phenos. The more stable the line is, the less variations. I have to admit, yours is excessive. The process of making Female seed requires stressing a female plant to produce pollen (via CS or STS). It's cool to know all the seeds are female, but that's when phenotypes from the parental lineage surfaces. So you end up with phenos from parents and grand parents, so the plants from the same seed batch are likely to be different.
