Is the DVD missing a special feature?

I saw the VHS and now the DVD, and I could've sworn there was a documentary on Topaz that talked about the scene where the Cuabn woman in the purple dress, and how they used piano wires to spread the ends of her dress like a flower.

This is nowhere to be found on the DVD version. The only "Behind the Scenes" is a 30 minute Leonard Maltin documentary.



So, is the DVD missing something the VHS once had, or did I imagine the documentary? (although I can't figure out where else would I learn about the purple dress scene)
