Inxi -Fza does not give full firmware information of drive

I have a Samsung 850 Pro 512 GB drive in my computer.
inxi -Fza gives:

 ID-2: /dev/sda maj-min: 8:0 vendor: Samsung model: SSD 850 PRO 512GB
    family: based SSDs size: 476.94 GiB block-size: physical: 512 B
    logical: 512 B sata: 3.1 speed: 6.0 Gb/s tech: SSD serial: <filter>
    fw-rev: 4B6Q temp: 21 C scheme: GPT

Firmware revision is EXM04B6Q.

Looks very, very, very close to me…I’m guessing the EXM0… part of it isn’t part of the version number…
