I have picked up a 1Tb SM961 (hp oem) NVME SSD. I looked up for the endurance rating in TBW, and surprisingly, my 10 minutes + googling wasn't able to find the information! Amazing to think company like Samsung sold so many drives to OEM clients without telling it's endurance rating. Perhaps the endurance changes between applications (by using higher/lower quality NAND chips)? Not that I expect to reach even 200TBW for its life but I am super curious now.
