That is an outstanding observation, Kolo mou, since we can speak of heresy in meaningful terms only with respect to matters concerning the revealed Trinitarian and Christological nature, i.e. that without which there is no Christian faith (i.e. the Nicene Creed). Purgatory,
Immaculate Conception, and Papal Infallibility are not required for the Christian Faith to be orthodox. Insisting otherwise elevates things that are of lesser nature to the level of the divine, which is itself heresy.
