Every VRTheme in the OP includes a complete set of icons so all icons are changedAll of the ones in the OP? I just want to be sure.
Edit: No they don't, the one I just installed did not change the menu button.
If an icon doesn't look its changed after flashing then the new menu icon is the same as the old one.
A lot of the softkey sets I've converted only include original icons for back, home, recent & search (not used on the N7) and use the stock icon for menu.
