Surprisingly, Apple’s Night Shift does not help in any way to fall asleep, according to a study. Intuitively, I thought of the opposite. When Apple launched this feature, in 2016, they said it would help. It seems it’s not the case after all. Will they backtrack and remove the feature in a future version? I highly doubt it. Many people do like this feature (I do on the iPhone, I hate it on the Mac), others like @Gruber don’t. What I don’t like is when the feature is in action, opening Photos abruptly turn the visual effect off. The effect is brutal as the screen turns blueish and cold because of the contrasting mode. I would prefer a more gentle disabling of the feature.
