When you're talking about source that was originally shot on NTSC video, which is effectively 480i, there would be little improvement over what your digital TV already shows you. Since your digital TV already displays 480i as 480p, the only difference in PQ would be the quality of the line-doubler in your TV vs. the one at the station.
The big problem with 480p is that many digital TVs incorrectly assume that all 480p is 16:9 and therefore lock into full mode which prevents the viewer from controlling the aspect ratio... so you end up with 4:3 stretched to 16:9 which is unwatchable.
