DarkNetwork vs Standard client

Hello.

I have some PCs with windows8.1 and SEP 14MP2. Few have "Standard Client" settings and others "Dark Network Client" settings.

On all Standard clients I have:
Virus and Spyware Protection July 3
Proactive Threat Protection June 27
Network and Host Exploit Mitigation July 3

On all Dark Network clients:
Virus and Spyware Protection July 3
Proactive Threat Protection June 27
Network and Host Exploit Mitigation June 28
(screenshots attached)

Can please someone advice, is it ok for DarkNetwork clients to not download "Network and Host Exploit Mitigation" defenitions from SEPM? 
Thank you in advance
