The first two in here[1] are reporting 3% of a 2TB drive in a couple months. And speculating what that would look like for a 256GB drive. So, not definitive, but if it does mean 24% in two months for a smaller drive, that's not great.
Edit: I suppose it makes sense that the people seeing lots of wear are the 2TB drive buyers. People that are willing to pay for that much NVME probably use it a lot.
