That's unlikely but possible. Static dischargers are here to discharge static electricity, and when you get a lightning strike (can be anywhere on the fuselage, sometimes one or more "burn away", that's what they are installed for. So this could be a sign of (very) intense lightning action, if the 3 were gone due to lightning. But as I mentioned above, could also be during the water-impact or during handling later.
