Well, there is an easy part and a harder part.
Easy part - the parameter to look at is "cur version"
# mmfsadm test readdescraw /dev/dm-14 | grep " original format"
original format version 1600, cur version 1700 (mgr 1700, helper 1700, mnode 1700)
The harder part is what version number = v2 and what matches version 1. The real answer is there is not a simple one, it is not really v1 vs v2 it is what feature you are interested in. Just one small example
4K Disk SECTOR support started in 1403
Dynamically enabling quotas started in 1404
The docs have some information on
