     inverted to make them stand out. Note: This option applies after the
     effects of all of mpv's color space transformation / tone mapping options,
     so it's a good idea to combine this with ``--tone-mapping=clip`` and use
-    ``--target-gamut`` to set the gamut to simulate. For example,

     gamut of a standard gamut (sRGB) display. This option also does not work
     well with ICC profiles, since the 3DLUTs are always generated against the
     source color space and have chromatically-accurate clipping built in.
