Your TV takes any of it's supported input types and converts it to the native resolution of the display, presumably 1920x1080. That's commonly called upscaling or upconverting; there is no precise definition. There is no control; it has to happen. No choice.
Blu-ray native video doesn't need any conversion, because it is already 1920x1080.
DVD video is stored on disc as 480i. The interlaced video must be deinterlaced to 480p, then that image is scaled to 1920x1080. Your TV will do it, or if your BR player has output resolution options (480i, 480p, 1080p, etc) some or all of the work can be done in the player.
Without testing to see if there are perceptible differences there is no way to prefer one way or another.
Calibrate the basic controls on your display when testing this.
