Systems and methods for adaptive color accuracy with multiple sensors to control a display's white point and to calibrate the display using pre-boot diagnostics

A memory storage device having program instructions stored thereon that, upon execution by one or more processors of an Information Handling System (IHS), cause the IHS to:

• receive a first measurement from a first Ambient Light Sensor (ALS) disposed on a display portion of the IHS;
• receive a second measurement from a second ALS, wherein the second ALS is configured to face the display portion in response to IHS being in a closed posture;
• determine if the first measurement and the second measurement are different from previous measurements by an amount greater than a threshold value;
• in response to the determination, select one of the first or second ALS sensors, wherein the selected sensor presents least variation from the previous measurements;
• calculate a correction factor for the selected ALS sensor using a lookup table (LUT) with color correction values and based upon context information;
• tag the selected ALS sensor as the primary sensor;
• and
• control a brightness of the display using a reading from the selected ALS sensor.
