Yes, it is only the DC that doesn't pull HomeDirectory and Shell via rfc2307. (when using winbindd) Member servers with winbindd do pull the desired values without problems, I have it setup like this and it works without problems.
I have only two ideas to solve your problem: either you don't allow logins from users on the DC or you switch over to sssd on the DC.
I suppose sssd should be suitable to achieve your desired results on the DC.

But you do have winbind in your nsswitch?

Lack of flexibility is my main problem. Unfortunately without restructuring how our home directories are set up, I need the flexibility. I need HomeDirectories etc to be pulled from the AD if I'm to retire our current LDAP servers and use Samba4 as a replacement.

Just to clarify, is it only the DC that doesn't return desired values of HomeDirectory and Shell?
I ask because my member server is returning the desired values, but I get the impression that it should not be from comments on the list.
Rowland was helping me with winbindd over the last few weeks and I got the impression that my Member Server should not be returning correct HomeDirectory and Shell - but it is - that is why I mentioned that I don't have SSSD installed - nor any other nsswitch back to our current LDAP. I need to know if what I am seeing is a freak of computing, or expected behaviour.
