Compared 0.34 and gallery in steam version (it is same in demo and closed beta)
There 187 poses in 0.34 out of which 25 is missing in steam version resulting in 162 poses. Number of poses had also their compatibility altered what makes comparing them ... fun.
Steam has 1 extra outfit for each girl - Alet NAPD police , Erika Funeral Violinist, Anya Pilot Bodysuit.
Harem mode has 167 poses based on the crafting list. There is certainly good number of new poses but it also means there is a lot of poses missing.
Wise guys probably going to mix in new poses with old one to make the patches look substantial.
It would be nice to compare the gallery poses with harem to see exactly what is new but it is hard to compare just on card alone :/
