In my getting Blu-ray picture or just Hi-Def picture?

[Αδάμ]

Hi I have 38'' Philips HDTV/LCD with 768P & my Playstation 3 with (40gb). I am also using (Philips HDMI-To-HDMI) cable to connect my HDTV & PS3 together for better picture & sound. I set my Playstation 3 to 720P instead of 1080i because, 720P is better. When I play "Planet Earth" on Blu-ray format, well.......I have a good eye & I am not like "wow this is amazing". Is it because I do not have 1080P resolution?

In my doing something wrong?
Playstation 3 it has Blu-ray drive.

It should be just right if you had calibrated your tv and aren't sitting to close
