So this turned out to be a known limitation as described in CSCvn41817. Basically, IOS XE is unable to advertise capability for Add-Paths for VPNv4 and VPNv6 AFI's. From IOS XE 17.9.x and later, VPNv4 and VPNv6 supports the "bgp additional-paths select" and "bgp additional-paths install" features. However, neither "bgp additional-paths send receive" nor "advertise additional-paths" are supported, making it a fractured and not very useful feature.
