No. You get extra melee damage because Invisibility automatically puts enemies in an unalert status towards you. Melee attacks on unalerted enemies are boosted in damage, something like 200% on charged attack.

So Invisibility it's self isn't buffing your melee damage. It's the side effect of enemies switching to an unalerted status that gives you the damage bonus.
