What's the capacity of your 960 EVO?
The 250GB max out at 3200/1500MB/s, while the 500GB at 3200/1800MB/s. and the 1TB at 3200/1900MB/s.
Are you comparing to Raid 0 setups?
How good is the airflow, even with a heatsink on the M.2 it can throttle, especially when you keep running benchmarks.
After focusing on my CPU speeds, I had to revert back to default BIOS settings. I re-enabled XMP, but did not set anything else. (I forgot about the settings you mentioned.)
So you made me curious. I just ran Samsung Magician, and it says performance results 3137 / 2010. It also says the interface is PCIe Gen. 3x4. Also noteworthy was a firmware update applied today, after just updating when new last week.
Did you peel the backing off of the thermal tape that was pre-installed on the heatsink? I was surprised to learn that the blue tape was indeed thermal tape. I removed the label from my SSD and the backing from the blue tape and installed.
Edit* I have a pro, but hope this is helpful. Perhaps mine is under performing as a pro since I'm not sure what the performance should be.

Figures seem fairly ballpark to me. Don't forget the max theoretical speed is exactly that, and you're close to it. Try updating the firmware as you say.
Leave the sticker on, you would need it in case of RMA, it also has a thin copper layer as heatsink
