At least in CD Project verse I think they do. The World of the Witcher, at least, states that the provinces were forced to adopt the Great Sun and certain principles of Nilfgaardian culture. The quote; "The peoples under the dominion of the empire were also expected to learn its official language and adopt elements of the victors' culture." Can't remember if this is ever actually referenced in game but it's been a long time since I played them.
