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.
scientific output returns real NDVI values from -1.0 to 1.0, build stats or DRA will display the image correctly
Use the Clip function to select an area from the GLS2010 enhanced image service, and run the NDVI tool on the clipped image.
