From your description you haven't turned off your accesibility preferences and are still overriding with a white background for display only. You've changed the background colour, but chosen not to see it. The preview presumably doesn't use accesibility preferences so it is a true preview of the actual canges.

Thanks.  This is the answer of course.

Presumably Edit, Background, Remove reverts to Accessibility or a white default.

case Background

  Edit:

     if Remove OR !DC

        // default

     else

       ...

  Default:

     // accessibility

would work but guess the case or if structure gives accessibility priority except for the Preview Pane which has a different display logic.

(Might be good to mention in the documentation on Edit, Background that accessibility takes priority and should be unchecked.  Or maybe the documentation already does mention that and, like the typical user, I didn't read it!)
