The DVD is better than the BD in every category, except for sharpness. I do think the original source is significantly more detailed, but the dvd transfer process blurred it for some reason.
(Also there are very rare deinterlacing errors (as the DVD is 29.97p, but the original source was probably 59.94i). Those errors exist in the BD ver as well.)

Just per episode cropping… which is inconsistent between scenes.
