I'm not sure how large your 720p LCD screen is but I've done some A/B testing of the same movie between blu-ray and dvd on my 56" 1080p LCD at normal viewing distance and the improvement is quite noticeable. Even though there is noticeable improvement in picture sharpness I find the color depth to be the main thing I appreciate.
That said movie production quality is a big factor also. For example on blu-ray you can clearly see how some of the non-cgi scenes in Transformers look grainy most likely do them trying to punch up the light of shots made in low light with lenses that were too slow.
