The top is the Blu-ray, below that is the terrestrial digital, below that the “up-convert”, and finally the abominable up-sized standard definition. Obviously you will need to scrutinise this completely expanded.
You can see the 6mb png here.
A little bit of caution is needed in looking at the three below the BD; the artefacts around the labels indicate they have come from a jpg source (though this comparison is saved as a lossless png, and the BD is clearly pristine).
However, you can easily make out the differences in any case. If not, get a bigger monitor: I can say it is night and day on a 27.
