I bet that they did not account for additive effect of a small percentage of light coming through each of a hundred or so windows.
I'm not sure it's an oversight or a calculated trade off. Windows that don't go completely dark is a feature: it is meant to allow others to see what's outside without disturbing seatmates. How much light is too much is subjective, isn't it?

Maybe the real oversight is not allowing airlines configure the maximum and minimum setting?
That's a possibility too. It's neither difficult, nor expensive to do a study of how much trnaamission od light into the cabin is acceptable for sleep. If it wasn't done, it was sloppy on the part of Boeing. Blaming a contractor as a poster did, is untenable.
