Not true. There is not one instance where angels were depicted as white smoke. Never. Not during Castiel possessing Jimmy Novak. Not when Castiel transferred from Claire Novak and back to Jimmy. Not when angels died. Not when Alastair was attempting to banish Castiel. The only semblance to white smoke we had was Anna's Grace and it was bluish in color. This was the grace and not the angel itself. All other instances depicted angels as white light. Even when Gadreel first possessed Sam this season, it was depicted as white light. There is no excuse for this mistake other than fan theory that the fall of the angels deformed them.
