I do not believe that religion plays any role in this society. I do not think that the values of this society are really compatible with religion.
This society is based on the idea that you live your life without thinking. It says that people should keep themselves entertained at all times by watching the parlour walls or by going to amusement parks or things like that.
Religion is something that really requires people to be still and contemplative at times. You cannot have religious experiences with the White Clown yelling at you. So I do not think that this society can really have much of a real religion.
