I think there is also the molars and general jaw shape to consider. Carnivores are not just identified by their fangs, they have generally a different structure and layout of their jaws that is made to lock into a prey animal or tear out pieces of flesh.
In contrast, many herbivores have teeth laid out to grind down plant matter (think cows or goats) and their mouths are laid out to chew off vegetation with very articulated lips to assist. Even if these camels have pointy fangs, the rest of their mouth would indicate they eat primarily plants.
