What do you call an evil on the inside but good on the outside utopia?

Example: The utopia in The Giver

The Giver was never a utopia.

Explanation:

In Lois Lowry's The Giver, we are introduced to a community that follows the idea of sameness. The citizens see no colors--literally. It was only until our main character, Jonas, recognized that the color of his friend's hair looked odd. The oddness of her hair was the same as the oddness of an apple.

The idea of Jonas' community was for it to be a utopia where everything is perfect and everyone is happy. There was no pain. No discrimination. No odd deaths. That is a utopia. But, the community was actually a dystopia. It seemed perfect on the outside, but no one experience joy or love or any of the things we do. No one felt or cared for anyone. They were assigned jobs. Jobs that they'd work for the rest of their miserable life. The may have not experienced pain or injustice, but that came at a cost--the memory of society.
