Seeking opinions on whether the bottom flange on a 70-73 front bumper should be painted body color or left in flat charcoal (natural endura color).

In an old "shark tank" thread here, Bill Oxley stated that the bottom flange should be unpainted, and this seems to make sense since it visually rounds out the opening between the valance and the bumper, and better hides the mounting bolts.

But I've yet to find a photo of an original car showing the flange left unpainted, and it seems the flange is painted on all the restored car photos I can find. Which way is factory correct?

Please see the area I am referring to in the attached photo.

Thanks!
