A "calamity" in Eorzea isn't just a a description of a devastating disaster; it's an historical designation formally assigned, and marks the transition from Astral to Umbral era.
The battle between Shinryu and Omega was not designated a calamity by the leaders and historians of Eorzea, and did not begin an Umbral era. Ergo, it is not a calamity. Largely, I would presume, because most of the damage they did was to one another and not to the world itself. There were some casualties, but not at a world-changing scale. And the surface of the world itself was not significantly changed apart from a few inflicted scars.
IIRC there have been some calamities in the past of similarly minor impact, but the difference between this event and those is the designation.
Still, most calamities are far more destructive. One was an ice age. One was a great flood. And one, of course, was Dalamud/Bahamut, which we can see just from touring the gameworld caused an order of magnitude more damage than Omega/Shinryu.
