Fan out the tuna on a large chilled platter. Arrange the baby arugula evenly over the tuna. Place the shaved Parmesan over the arugula. In a squeeze bottle, combine the soy sauce and the white truffle oil. Shake and drizzle the sauce over all the ingredients. Grind the black peppercorns over the dish. Serve cold.
