An arranger keyboard is not a fair comparison because all those sounds are controlled live by the player. Things like velocity switching for example. Velocity switching is based on your touch on the keys. My older Kurzweil has a three layer piano for example but the newer boards have more than that. Hit the keys soft you get layer 1, harder you get 1 and 2 and the hardest gets all three. Each layer is a separate recording so different players will get a different sound out of the Genos while playing the exact same notes. And that's just the beginning, the Genos has articulations that are controllable too.
