No, no macOS. I just wouldn't expect that the software would make such a difference. I also wasn't sparing with that machine, went gigabytes into the swap regularly, the SSD was often at 85-90% capacity, and yet I was nowhere near depleting the reserved blocks and had zero problems after years of use. (I can't remember when exactly I bought the SSD but I think it was 2015 or 2016 and I used it until 2023.) I guess it's possible, it just sounded like individual bad luck to me. My impression has been that you really have to write a lot to wear out the expected life of a non-ancient SSD.
