Overt meaning publishing our narcissism uncensored, rather than acknowledging that we're naturally concerned with our outward appearance and status but see the value in balancing it with some modesty lest life become a silopsist shitshow.

You could argue that a painting, while expensive, is less overt in a spatial sense than making images of yourself available to practically any person in any location at any time. It's multi-dimensional vanity repeated ad nauseam because it costs practically nothing. Paintings are limited to specific times and locations in space-time.
