Will 540s SSD compress data?

I have a intel 540s SSD. I found that the Total NAND Writes is smaller than the Host Writes from SMART in Intel SSD Toolbox.

In my situation, the Total NAND Writes is 805, and the Host Writes is 1449.22 GB. If the write amplification factor is 805/1449.22=0.56, which is smaller than 1, the data might be compressed by the SSD itself. Is my calculation right?

I find some users of 530 SSD or 535 SSD have a write amplification factor larger than 1 in this forum, so I want to know whether it is possible for 540s SSD to compress data.

Thank you!
