Difference in area calculation geometryService vs ST_AREA

Hi all, I keep getting small differences in calculating the area of a feature. Using the geometryservice (with a geometry from FeatureService) from the esri API (3.17), the result of an area calculation differs slightly from running ST_AREA(SHAPE) directly on my Oracle database. Parameters used (spatial reference, polygons etc.) are all the same. Any ideas what could be causing this?
