You mean you 'stand to be corrected'? Ok...correction coming up. There's a massive improvement from DVD to Blu-ray. I have both. The colours are so rich and bright on the Blu-ray it feels like a different movie. Well worth getting.
Question for you - are you comparing it (the blu-ray version) to the original DVD release that came out in '03, or the 2-disc special edition which came in the letterbox format? Just curious.
