He may have, but the general consensus is that Messi was not up to standard throughout that world cup. Of course, he definitely has very high standards compared to anyone else but Ronaldo.
His only goals came in the group stage and throughout the knockout stage it was generally regarded as a disappointment, to the point that many of his own supporters (Maradona and Blatter no less, who do not hide their love for Messi at any point) saw him winning the golden ball as surprising and unjustified, and to the point that Messi was seemingly resistant to receive the trophy (but then I rarely if ever see him look arrogant). There are reports of other players such as Di Maria and Mascherano (and even Romero!) being Argentina's best player in 2014.
