It's problematic to make judgements based on a single frame only, but for archiving I would definitely keep the retail (DVD) variant and make any tweaks (brightness, contrast, saturation) during viewing on the PC or TV as you prefer.
The TV version has clipped blues (e.g. the sky), and the black level of the active picture appears to be offset too high. The picture looks washed to me (e.g. the red light on the police car).
The TV variant also tends to producing illegal RGB triplets when decoded to RGB (sky for example), although it's minor for this picture, and it depends on the player how 'smart' these violations will be dealt with for playback.

Edit: The TV variant looks perhaps sharper but it has sharpening artefacts like halos, best seen on vertical edges. I don't see more real details.
