For datasets defined on faces, one can choose to interpolate data to vertices with neighbour average method. When no data interpolation method is chosen, each pixel on a single face has a single value/color. With data on vertices, the rendering for each pixel is interpolated from the values on the vertices, making smoother figures.
Use mesh contours styling panel to switch between the data interpolation methods.
