It is very interesting, because I, too, watch it and do not know why there was a downgrade product version scep to 4.7.214.0 in sccm1602, although according to https://support.microsoft.com/en-us/kb/3153224should be anti-malware client version to 4.9.0219.0. Also on a clean server installation sccm 1602 we have source distribution version anti-malware client 4.7.214.0.
