1. A system comprising:
a memory; and
a processing device, operatively coupled with the memory, the processing device to:
process, using a trained machine learning model, an input corresponding to an image having a first pixel value range to generate a first output comprising a first expansion map in a first channel and a second output comprising a second expansion map in a second channel;
expand the image to generate image data corresponding to a second pixel value range, wherein the second pixel value range is larger than the first pixel value range;
update the image data by applying a filter to reduce one or more banding artifacts in the image data based on the first expansion map; and
update the image data by modifying a luminance of a region of the expanded image based on the second expansion map.
