Ah, no :)

    Bug 401754 – Port Hue, Saturation, Value to CIE LCH

    When using GEGL for the projection, use CIE LCH for the Hue,
    Saturation and Value layer modes, just as we already do for the Color
    layer mode. The Value layer mode will later be renamed to Lightness
    since that is the semantics it has now.
