As you posted, all skins and composite/profile fills are shown properly in a 3D Document view.
While it would be nice to have live 3D views showing this - wished for for many years, including by me - for real work, the 3DD is good enough for me. You can define as many 3DD views as you need and/or have a view that you simply right-click/redefine to see the skins in your current 3D window.
