You're talking apples and oranges though. Your state rights were protected. Your Federal rights are another matter. It doesn't matter whether your state calls it a domestic violence case or not for purposes of the Federal government and VAWA and Lautenberg. The definition of a domestic violence offense under Federal law is found in 18 USC 921 in subsection 33 which says:
"the term “misdemeanor crime of domestic violence” means an offense that—
(i) is a misdemeanor under Federal, State, or Tribal  law; and
(ii) has, as an element, the use or attempted use of physical force, or the threatened use of a deadly weapon, committed by a current or former spouse, parent, or guardian of the victim, by a person with whom the victim shares a child in common, by a person who is cohabiting with or has cohabited with the victim as a spouse, parent, or guardian, or by a person similarly situated to a spouse, parent, or guardian of the victim."
So to be clear, it doesn't matter what your state labels the offense. If it conforms to a domestic violence offense under the Federal definition, it can cost you your gun rights. You can appeal, as indicated on the basis that your offense has been both pardoned, expunged and sealed and is now a nullity.
