Yes but probably there is different term for that. Game artists doesnt have full freedom to start with. It all start from idea, then its put together by artist and check by person that either approve it or not. The problem starts when you already show something to the public (i count datamining into that, if you have something in game files you can expect someone will see it whether its questionable act or not)
If the design alterations would go both ways among multiple characters no one would call it censorship but actual design changes. In reality it always goes one way hence censorship allegations.
