Why does the POCO F7 Ultra have a lower color temperature/yellow screen display at night when in Cycle reading mode?

Thank you for your support. We are committed to providing the best experience and are pleased that you chose the phone.
The Cycle Reading mode will dynamically adjust the screen color temperature to improve the screen experience and enhance your comfort at different times and scenarios during the day. If you want to further adjust the screen color temperature or fix it at a certain color temperature, you can switch to the Classic mode and customize the color temperature. Thank you for your use.
