Maybe it does not matter at all. If V5 does not look any good, why need an exporter

At this point, nothing Genesis will look as good in Poser as it does in DS4.  Well... maybe in T-pose.
Maybe that will change in the future, but for now, once you start posing the figures in Poser, you will see anomalies that you wont see in DAZ Studio.
Poser's rendertime smoothing can fix some of it, but it wont work on everything.
