In you overview of High Sierra you say -
In macOS High Sierra, there are expanded integrations with photo editing apps like Photoshop and Pixelmator. When you open a picture in a third-party photo editing app directly from Photos, all edits made are automatically saved in the Photos library.
If you are referring to the ability to "edit in" a third party program of choice then I can see no way to get the edited image to save back to Photos. I have tried with Topaz, Luminar, and Affinity. It certainly does not happen automatically.
