color profile generated by DisplayCAL

SUMMARY

My monitors are calibrated with DisplayCAL + DataColor Spyder 5. This means it load a color profile when the system boots. When it is time to shift night color, the color profile is reset and becomes bluish, and then gradually turns warmer.

STEPS TO REPRODUCE
1. Calibrate your monitor with DisplayCAL. If you don't have a device, you can try the color profile in attachment.
2. Wait the night color start.
3. Observe the transition.

OBSERVED RESULT
The color was first reset to default, which is usually more cold/bluish than calibrated color, and then it turns warm gradually.

EXPECTED RESULT
The color should change smoothly from the calibrated color to night color.
