It is my understanding that this was "by design". I.e. that if you work after the sun is set, it's bad for your natural sleep cycle for you to stare at a monitor screen which emits light that looks like the light coming from the sun.
By tying the emitted color from the screen to the rising and setting of the sun, your brain isn't affect by this any more. This doesn't mean that you have to go to bed when the sun sets and your monitor turns yellow - it just means that you increased your chances of feeling tired at a more natural point during the evening.
I'm a long time f.lux user and have happily accepted the yellow sun set on my monitor when the sun outside set. I've even worked long hours with this setting since it's a great ease on the eyes. If you ever worked at night with this setting for a couple of hours and then tried to switch of f.lux, you will feel your eye becoming VERY sore. Only then do you realize how uncomfortable the normal light from your monitor is.
When I had a problem with flux dimming my monitor too early, I just changed the intensity so it didn't get too orange. Just taking a little of the blue off still helps.
