What it is is based on the applicable law and the definitions therein, and those vary by state. In my state, an evaluation must state prominently that it is not an appraisal, but it is not the label that determines what it is.
This is an important idea which, once considered, provides all the clarity it takes to resolve this controversy.
USPAP is about the appraiser's conduct when acting in that role. It is the actions of the individual and the expectation of the users for those actions which are meaningful. Not the various labels in use in various references for these actions.
Not even the appraisal profession owns the entirety of the term "appraisal". That term has different meanings in different references and contexts. It means one thing in our professional standards and something different when cited in various areas of the law, rule and regulation.
For example, there's the USPAP definition of appraisal refers specifically to the appraiser's process of developing an opinion of value:

USPAP uses a separate reference for "Report", that reference also being very generic in scope.
-------------
And then there's the definition of "appraisal" as found in (for example) Florida's statutes for their licensees. That reference includes more elements than just the "development" side of the opinions and conclusion, apparently to also include the reporting elements:
----------------
North Carolina's definition varies from the definition used in Florida because it more closely parallels the USPAP delineation between development and reporting:

--------------
California has a definition for appraisal that's also similar to the USPAP definition but (unlike USPAP) they have no explicit definition of "Appraisal Report" or "Report".
