It is really an unfortunate over-engineering in the PNG format to include gamma correction. So many problems would have been avoided if PNGs just stored RGB values and let the renderer/OS/driver/screen decide how to display it. Trying to do gamma correction based on various guesses about screens just lead to jarring color inconsistencies. Here is great article about it. It is a few years old, so some of the problems are fixed now. https://hsivonen.fi/png-gamma/ https://hsivonen.fi/png-gamma/
