comment Pull-back of reflexive sheaves
This sort of issue and related problems come up a lot in practice (for instance in base change). I'll try to write down a reasonable answer giving some examples of techniques for showing this unless someone beats me to it. In the meantime, do you have some particular sheaves in mind? (Relative) canonical sheaves for instance?
