Overexposure == clipping. When any one channel gets clipped, you have
overexposure.  IMHO, #4 is the way to go.

The same thing is true for clipping on the bottom end. Take a bright color,
like (250,10,10). When this color is darkened by the amount of 50, it changes
to (200,0,0). That color looks quite different, due to clipping. And because it
is a fairly bright color, this form of clipping is very well visible.
Therefore, it should be indicated as being underexposed.

So, I'd say:

if (expoSettings->underExposureIndicator && 
     pix.red() == 0 || pix.green() == 0 || pix.blue() == 0)
