It's my understanding that while some changes have been made over time to Eastern liturgies, it is nowhere near the order of magnitude of the Novus Ordo changes to the Tridentine missal.
One of the main errors of V2, on a practical level, was the destruction of unity, by allowing the novus ordo to be said in the vernacular but also with multiple canons/options. It was a complete reversal of Quo Primum’s main goal, ie codification of the rite for increased unity.
Post V2, The Eastern liturgies were allowed to “recover their patrimony” which led them to reject any reforms/unity of Quo Primum with the Latin rite and to return to the pre-1500s rite (or even before). Result - there were definitely changes in the Eastern rites, maybe not as drastic as the novus ordo, but unity in prayer was destroyed.
