samba - Jul 2016 - Can the 'operatingSystemVersion' value of DC computers in LDAP server keeps up to date?

When I use ldbsearch to get the operatingSystemVersion information, I got
'4.0.6', but I'm running samba-4.4.5 now.

It seems that this information stayed at the version number when I provisioned
the domain.
Can this version number keeps up to date when I upgraded samba server?
I can write a small script and scheduled it to change this information
periodically, but if there's an internal way to change it, that would be
great!

# ldbsearch -H /usr/local/samba/private/sam.ldb  -b 'DC=MYDOMAIN,DC=com'
'(&(samAccountType=805306369)(primaryGroupId=516)(objectCategory=computer))'

# record 1
