The following video bitrate graph was generated by BDInfo 0.5.3:
At the top of each is the full frame (suitably shrunk down) used in the comparison, with a 250 pixel wide detail from the frame underneath. The left side is from the PAL DVD. The image was captured digitally from the disc, scaled up from its native 720 by 576 resolution to 1,024 by 576 (to present in the correct aspect ratio) by the application. I then scaled it, in order for it to be comparable to the Blu-ray version, to 1,920 pixels wide.
The detail is from that last scaled version, and has not been rescaled again. The right side is from the Australian Blu-ray. This has not been scaled at all. Different applications were used to capture the two frames, however in general encodes taken from the same master do tend to look largely similar. In this comparison there are clear differences in the colour cast between the two versions, and the brightness levels.
For visitors from NTSC lands, generally the PAL DVD is just a touch sharper than the NTSC DVD.
Interestingly, some rebalancing of light levels and coour appear to have taken place, and in this frame seem to have blown out the detail for the outdoors. See, for example, the loss of the shop name above the green door out on the street:
