After review by the development team, it has been determined that this issue is related to a known limitation with the software that lies outside of Esri's control. The issue's Additional Information section may contain further explanation.
Cell values in the output curvature result are correctly calculated based on the curvature equation http://desktop.arcgis.com/en/arcmap/latest/tools/spatial-analyst-toolbox/how-curvature-works.htm
The values are very high because cell size and thus L value in the equation is very small, which is 1 in this case.
Running the tool from the Neighborhood tool that smoothes the data produces better results.
