>Orthodox do not believe in purgatory
See >>852886
>Orthodox do not believe in transubstantiation
They do believe that the eucharist is Christ's body, they just don't bother to name it or specify it
>Orthodox do not believe in the filioque
Some reject it as heresy, but some don't consider it a Church-dividing issue and hold that Catholic understanding of it is orthodox
>Orthodox do not believe in original sin
They do, but they use the name differently and some have a twisted view on what Catholicism teaches
>Orthodox do not believe in the immaculate conception
Not a dogma for them, but if understood well, most of them will agree. They do hold that she never commited any sin
>Orthodox do not use unleavened bread in the divine liturgy, Orthodox do not celebrate Pascha before the Jewish Passover
Both true for Eastern Catholics
>Orthodox involve children in the entire life of the Church unlike Catholics
Quite uncharitable description, but again, true for Eastern Catholics as well
>Orthodox do not believe in the use of statues or images of God the Father
Minor issue for Roman Catholics and probably Eastern Catholics would also object to images of God the Father, as they have a more developed tradition of icons
>Orthodox use the LXX instead of the Vulgate for the OT
See: >>852884
But yeah, I agree, Orthodoxy is not just "Catholicism without a pope". You just listed the wrong reasons
