I have Firmware 01.00.0000 does that mean I don't need NLD

I bought a used Mavic 2 Pro on Ebay. Downloaded DJI Go 4 and didn't upgarde any firmware when I installed it. Firmware was 01.00.0100 or so I thought when I originally emailed NLD. Opened DJI Assistant 2 for Mavic today and it said my firmware is 01.00.0000. Not sure if that is good or not? Confused if having 01.00.01000 is better so I can have the NFZ Patch and Speed boost or if having the 01.00.0000 already has both of these since it is the first version?

From my understanding;

Upgrade to .100 via NLD
Unlock that version to allow FCC/Boost/NFZ etc by buying the NLD activation key.

Then avoid upgrading via Go 4 and DJI Assistant.

Awesome. Thanks
