1. An electronic device comprising:
an electronic display panel of an electronic display configured to display image data according to emission profiles;
processing circuitry configured to:
multiply an average pixel level or average pixel luminance of respective rows of the image data to be displayed on the electronic display with respect to elements of a mask defined according to one or more of the emission profiles;
accumulate the results to obtain an average pixel level or average pixel luminance of the image data to be displayed on the electronic display; and
perform an operation related to the electronic display panel based at least in part on the accumulated results.
