ok, this is a bit of a mess as you are both right and wrong
NVME standard in general does not use the SMART system for health reporting but it does have health reporting. My understanding is that the SMART standard is old and really complex (to much so) with a lot of crazy stuff added in over the years hard drive development. The people who developed the NVME standard decided they didn't want to even try and use it because of problems
in that it would make them build in stuff they didn't want into the NVME drives. (scratch head, my understanding on this and why is minimal) However they did build in all the health reporting stuff that you would need. I'm assuming based on below that some of the smart software is being modified to read some NVME information now.

While smart and sata drives have been around for 3+ decades and is a mature tech, NVME storage is relativly new and doesn't use the sata specification
so it's not as cohesive at a user level yet but it is there.
