Could the Bunker Dwellers become noticeably different from Wastelanders?

So, in my world, there are a group of people, mostly unknown to the rest of the world, who took shelter from the apocalypse 90 years ago in great underground bunkers. Compared to the rest of the Wasteland, they live in a utopia (except for all the xenophobia, fascism, and euthanasia). They have access to clean water, plentiful food, and so on. Basically, they live a modern style of life, while the rest of the world has returned to early 19th century. So, my question is, considering their lifestyle, would the Bunker Dwellers have any noticeable genetic differences to Wastelanders, after 3-4 generations underground?
