Yeah, I know that would be best for such comparison course. The problem is that within the DeEd, I dare say there isn't a single frame that has the same or even similar colours, brightness and contrast as the BD. And all this adds to the perception of detail, so simply sizing a BD image down to 720p and then back to 1080p up wouldn't give you the right idea on the amount of detail in DeEd v2.0. But still, here it is; left untouched BD 1080p, right the same screenshot downscaled to 720p and then saved, closed, opened again and upscaled back to 1080p:

To me the 720p upscale has more detail than the official Blu-ray, maybe it's just me.
