UDPATE: At least system screenshots under Windows 11 do not have a color profile attached, and if they did, assigning sRGB would be totally wrong. If you then would want to have the screenshots in sRGB gamut (for public use), you would need to convert them from the display color gamut to sRGB. On macOS, screenshots typically have display color profile embedded and called just 'Display'. one provided by the manufacturer of the display). icm file that your calibrator has created, or something more generic indicating the kind of display you have (e.g. If you have a calibrated display this would typically be an. If you want to open the screenshots in Affinity Photo in their original appearance, you would need to assign them your display color profile when you open them for editing.

So you would get something like this (the difference can only be simulated here on the forum since all images are narrowed down to sRGB gamut, so the saturation below has been decreased by image manipulation): That would result in desaturated colors since your wide gamut display's color appearance cannot be fully represented in sRGB. Based on your screenshot, you are using the default sRGB.

The reason your images look a bit desaturated might be that your display is wide gamut, which means that screenshots without a display color profile embedded, if opened in Affinity Photo, would be assigned with whatever color profile you have defined in Preferences > Color.
