+*<core><hdr>* [yes|no]
+	Automatically enable HDR support on outputs when configuring them,
+	where supported by the particular output device and display. Default
+	is no.
+
+	Note: Enabling this option will also currently make all non-HDR
+	outputs render to 10 bits per channel as well, but still sRGB.
+	Any configuration with `wlr-randr` or `kanshi` does not seem to
+	support passing this flag to my knowledge, so the only way to
+	override it is to enable this option.
+
 *<core><reuseOutputMode>* [yes|no]
 	Try to re-use the existing output mode (resolution / refresh rate).
 	This may prevent unnecessary screenblank delays when starting labwc
