If the numbers were coordinates, who's to say they aren't coordinates on some other planet than Earth, or are not conventional coordinates as we would interpret them at all (i.e. they could be asari or Council standard coordinates, or pertain to a location in a given solar system, cluster, or the galaxy itself rather than a specific planet)?

The mass relay age theory is more likely because of the context of the CDN report, and the screen displaying the numbers is also showing a mass relay. I don't think the mass relay is there as a screensaver.

As for image #3, I don't see anything particularly remarkable. Obviously it's on a planet where a mission in Arrival takes place, but that's all I think we can say about it.
