Healing a Dhampir with Treat Wounds pretty clearly works.
Now, healing a Dhampir with the Heal or Harm spells - that's some gray area there.
There's no grey area there either.
- Heal is Vitality and Harm is Void. Both spells are clearly tagged and include such wording in their respective spell descriptions.
- Dhampir had the Void Healing effect, which states they are healed by Void and hurt by Vitality.
