Do you mean green Cory ( aka Bronze Cory )
Corydoras aeneus ?
Most albinos are also C aeneus.
So prob not a hybrid they would be just crosses from 2 colors of the same species.
If they were hybrids, you prob shouldn't sell them. Too easy for them to pollute the gene pool as there are a ton of lookalike Cories that are hard to tell apart as it is.
An example are Synodontis cats. There are so many hybrids being sold as true Synos, it's hard to find "real" ones.
