Pull them up and you'll see FPN.
BUT: if I pull our aging Red Scarlet up to the same levels I see more random noise on that than the peaks of FPN from your UM. Why no FPN on the Scarlet? Because it needs 13 (!) minutes (!) for black shading. And you'll need to store different shading results for changing temperatures or off-speed. That's how they avoid FPN.
And I can still remember it's price when it was new and how cheap that was compared to Sony or Arri.
