Question on Photos download options via iCloud.com

I’ve read the support documentation and some posts but, forgive me, I’m still not clear on this.

In the photos download options for iCloud.com , there are options for downloading “Unmodified Originals” and for downloading “Including Edits” with “Highest Resolution.”  Does the “Highest Resolution “ option also include getting the “Unmodified Originals”? 

If you did a Venn Diagram, would the circle representing “Unmodified Originals” be completely contained in the circle representing “Highest Resolution”?

Thanks.
