Blu-Ray and HD-DVD are sharper than standard DVD, especially on bigger screens and/or shorter viewing distance, when you have side-by-side comparison.
Some DVD players upscale the DVD to 1080P very well such that when watching it alone the picture is very sharp. Most people are happy with standard DVD that why Blu-Ray didn't catch on as well as it should.
