How does Roon Identify Albums from users input?

As an enthusiast of Australia Jazz Albums I have quite a few Albums that Roon fails to find a match/identify.

If I manually label an album, will Roon ever pick up my input and update their database?

I have an Album where Roon has identified the Album but it has errors (two tracks are switched) do I have to report this as an error for Roon to fix their DB?

Currently, there’s no direct feedback channel which would bring your local changes into the Roon metadata cloud.

What’s possible is to enter data at musicbrainz - Roon uses musicbrainz as a source.
