Interesting that only with Win11 users get some advanced options for SDR but potentially wide-gamut images, on std 8 bpc displays with ICC color management === quoting Microsoft ==== In particular, by default your ICC profile-based app is restricted to the sRGB gamut, even if the monitor is actually wider gamut. Windows also provides an ICC compatibility helper that can give your ICC app access to the display’s entire gamut. For more info, see the Display ICC profile compatibility helper <https://learn.microsoft.com/en-us/windows/win32/wcs/advanced-color-icc-profiles> section in this topic. {...} Display ICC profile compatibility helper When Advanced Color is active, Windows provides a compatibility helper for display ICC profiles that provides access to the display's entire gamut. In that way your app continues to get accurate and wide gamut colors up to the reported capability of the display—the same functionality that's available on calibrated wide gamut monitors in legacy non-Advanced Color mode today. Without that helper, your app will be limited to default behavior, which is sRGB (see ICC profile default behavior with Advanced Color <https://learn.microsoft.com/en-us/windows/win32/wcs/advanced-color-icc-profiles#icc-profile-default-behavior-with-advanced-color> ). That helper is available starting with Windows 11. It doesn't provide other benefits of Advanced Color including access to higher precision/bit-depth or high dynamic range—you'll need to modify your app to be Advanced Color-aware. ===== Also interesting that MS uses some gpu hardware for this task, not just shaders alone? At least this is how I interpret hw requirements .... AMD after RX400, but much more recent Intel and Pascal+ for Nvidia ....
