1. A method, comprising:
determining, by a device, a first calibrated brightness value for a display that is displaying bright content based at least in part on:
displaying, by the device, first calibration content that includes one or more first calibration frames with a first background that approximately corresponds to white, and
adjusting, by the device and while the first calibration content is displayed, a first brightness value of the display until a first measured pupil size of a user of the display matches a first target pupil size, wherein the first calibrated brightness value is based at least in part on the first brightness value of the display when the first measured pupil size of the user matches the first target pupil size;
determining, by the device, a second calibrated brightness value for the display that is displaying dark content based at least in part on:
displaying, by the device, second calibration content that includes one or more second calibration frames with a second background that approximately corresponds to black, and
adjusting, by the device and while the second calibration content is displayed, a second brightness value of the display until a second measured pupil size of the user matches a second target pupil size, wherein the second calibrated brightness value is based at least in part on the second brightness value of the display when the second measured pupil size of the user matches the second target pupil size;
calculating, by the device, a metric value for content to be displayed based upon pixel values of the content; and
adjusting, by the device, a brightness value of the display based at least in part on the first calibrated brightness value, the second calibrated brightness value, and the metric value.
