1. An electronic device comprising:
an electronic display comprising a pixel and configured to display an image based on compensated image data; and
image processing circuitry communicatively coupled to the electronic display and configured to:
receive image data of an image frame to be displayed, the image data comprising a pixel value corresponding to the pixel;
determine a gain value for the pixel based on an aging value of the pixel, wherein the aging value is based on previously displayed pixel values of the pixel;
adjust the gain value based on the pixel value to generate an adjusted gain value, wherein adjusting the gain value comprises applying a two-dimensional look-up-table (2D LUT) based on the gain value and the pixel value; and
adjust the pixel value of the image data based on the adjusted gain value to generate, at least in part, the compensated image data.
