The info we are given in the show is from the perspective of the characters though, so if Weiss thinks Winter is her sister that's what we'll be told even if it's not true.

Winter does seem rather motherly in a way that could be interpreted as her secretly being Weiss' mom. But I agree that's somewhat typical older sister behaviour and that it's likely that Winter's motherly/authoritive behaviour was the result of a large age gap between the sisters and a strict code of social conduct based on their backgrounds as members of an upper class family.
