+        This creates a pre-defined image description for the so-called
+        Windows-BT.2100 stimulus encoding. This comes from the Windows 10
+        handling of its own definition of a BT.2100 color space for an HDR
+        screen driven in BT.2100/PQ signalling mode.
+
+        Windows-BT.2100 uses BT.2020 color primaries and white point.
+        The transfer characteristic is st2084_pq.
+
+        Windows-BT.2100 is generally displayed by Windows 10 without any
+        adjustments to the signal to account for viewing conditions.
+
+        The reference white level of Windows-BT.2100 is unknown. If a
+        reference white level must be assumed for compositor processing, it
+        should be 203 cd/m² of Report ITU-R BT.2408-7.
+
+        The target color volume of Windows-BT.2100 is unknown. The color gamut
+        may be anything up to BT.2100.
+
+        This request can be used when the compositor advertises
+        wp_color_manager_v1.feature.windows_bt2100.
+        Otherwise this request raises the protocol error unsupported_feature.
+
+        The resulting image description object does not allow get_information
