Let me clarify, I had a drain and fill performed at the local dealer. They did use genuine NS-2 fluid. It is getting cold here in CO, and is most audible when the engine is 2-4 bars warm on the temperature gauge. The noise is there at full operating temperature, but it is much less audible.
Edit: Also when I had the fluid drain and fill, the fluid was a half quart low. I took the car to a different dealer when I learned that the dealer in town kind of has a shoddy service department. The new dealer inspected the fluid, and said it was NS-2 fluid, it was just a half quart low. I was informed it didn't look contaminated at all. Once they topped the fluid off, the noise was quieter, but it is still there. I'm wondering if all CVTs make this noise, but the low cvt fluid made it more noticeable, and now that I know what it sounds like my mind is playing tricks on me. As of now, I've put about 1000 miles on my car since the incident (happened at 57k), and the noise has not gotten any worse. I should probably take it in though, I scheduled an appointment to see if there is a problem. If they drop the pan, I'd have to pay for another fluid change, but I'd rather have that than a CVT replacement along the road
