Does 1 Kings 15:5 suggest that King David was exempt from following some commandments?

We read in 1 Kings 15:5 that King David had obeyed all the Commandments except in the case of Uriah the Hettite, during his lifetime. The circumstances leading to the death of Uriah in battle were meticulously executed by David who had coveted his wife Bathsheba against the 9th Commandment, after having slept with the married lady against the 6th Commandment. On the death of Uriah, David broke the 5th Commandment, by having consciously planned and staged the battle scene (2 Samuel 11). As such, the victims of David's sins were both Uriah and his widow Bathsheba. But the mention only of Uriah in 1 Kings 15, makes one wonder if David, in the capacity of King, was exempt from the 6th and 9th Commandments. **Question**: According to Catholic scholars, does 1 Kings 15:5 suggest that King David was exempt from following some of the Ten Commandments?
