Exactly. We can call oversampling “digital zoom”.

It does not add new information (the oversampled image should look exactly the same as the original), it just allows representing finer details in the image or segmentation. For example, if you apply a sharpening filter then you can enhance finer details, or if you segment structures, you can represent thinner walls or smaller vessels.
