smartctl lies that NVME has lifespan of ~2800TBW? What is the real lifespan of my NVME?

smartctl -x on my Samsung SSD 860 EVO M.2 2TB shows:

A paltry 28TB written sounds a little low for the past year I've had this NVME but it's believable. However, the Percentaged Used Endurance Indicator is only at 1%. That would suggest there's still around 100x that or 2800TBW left in this device, which is more than twice the rated 1200TBW so it can't be a rounding error. Is smartctl lying? (Not that it would lie; I mean, is my NVME lying to smartctl, is smartctl misinterpreting my NVME, etc and etc?) How do I find out the real TBW life remaining in my NVME for sure?
