[Cin] Color management .. in windows 11!

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

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 ....
