I'm sorry, but you are mistaken. Iran is the country, not their ethnicity. Yes, ethnic Persians call themselves Persian instead of Iranian, but they will tell you they are from Iran. My husband said that within Iran, there has been ethnic Persians, just as there are ethnic Turkmens, Kurds, Armenians, Azerbaijanis, Arabs, Jews, etc. in Iran, along with ethnic Iranians. My husband and his family are ethnic Persians. Thre of my husbands closest friends are ethnic Kurdish, Armenian, and ethnic Turkmens respectively who are from Iran. Another of his friends from Iran told me himself, "I'm Arab from Iran."
