Resolution Note (2022.1.X):
This behavior is by design. In the documentation we have "This function is called before the imported Prefab is created in the Library folder and before it is written to disk" => the imported Prefab that is saved in Library folder contains all the changes made in OnPostprocessPrefab, but the original asset remains unchanged.
Prefab Mode (isolation) displays the prefab asset as it is the Assets folder which doesn't contain the changes made by OnPostprocessPrefab
