My ps3 bluray doesnt look as good as the bluray player i use to have?

I first bought a samsung bluray player and the picture was awesome. I decided to sell it and buy a ps3 instead because the ps3 has a bluray also , but know the movies dont look as good as the samsun , im trying to figure out why because all the blogs say the video quality should be the same! But it really doesnt look the same , any ideas?
