When the display configuration, the window's display path or its advanced-colour state can't be
read, `monitor_color` answered with the monitor's profile as if Windows weren't colour-managing the
desktop. If it was (HDR, Auto Color Management), previews were converted twice. It now answers
`Unknown`, as the crate's other failures do, so previews stay sRGB (Windows 10 before 1709 and
drivers that don't report the state included).
