Is the Best Buy Blu-ray demo disc enhanced?

Just got back from my local Best Buy. For fun I was watching one of the Blu-Ray demo disks on a Sony LCD. Anyway, the disk was obviously a promo thing for Blu-Ray, showing various movie clips and sound demo's.

What shocked me though was the clarity of the movie clips they showed, particularly from Spiderman 3 and Pirates 2. I've seen both of these movies on Blu-Ray on my PS3, but the differences between the full length features and these clips were remarkable. The details and color in these clips was almost overwhelming, better than any HD broadcast I've seen. Now my TV at home is only 720p but I didn't think the difference between 720p and 1080p was supposed to THAT drastic.

So my question is this: Is this Demo-disk using some uncompressed version of these films for the short demo clips? Will there be a format one day that allows regular blu-rays to have these uncompressed versions?
