It does not.
"If you don't accept me blatantly lying about the contents of a law, you reject the Faith!"
Are you actually mentally unwell?
Quo Primum does not refer to "substantial change", nor is there any dogma or tradition(I don't think you even know what this means, the way you use it) that it does. It bars any change to the Missal at all. Yet Pope St. Pius V himself and other popes later changed it. How could this be? Oh yes, because papal bulls cannot restrict the power of the pope itself, and that was never the intention of Quo Primum. New bulls can override, modify, abrogate old ones at the pope's leisure.
As per Quo Primum
"[...] whereas, by this present Constitution, which will be valid henceforth, now, and forever, We order and enjoin that nothing must be added to Our recently published Missal, nothing omitted from it, nor anything whatsoever be changed within it under the penalty of Our displeasure.
"[...] Therefore, no one whosoever is permitted to alter this notice of Our permission, statute, ordinance, command, precept, grant, indult, declaration, will, decree, and prohibition. Would anyone, however, presume to commit such an act, he should know that he will incur the wrath of Almighty God and of the Blessed Apostles Peter and Paul."
We only need to look at the counter church, today and for the past 51 years, to see this very wrath upon her.
