Other than the form factor (DVI cable looks clunkier) and the fact that HDMI also carries audio.

Is the video signal better?

For most applications, DVI and HDMI are both the same picture quality wise. The only difference is the connection type and the fact that HDMI can carry both video and audio.

DVI and HDMI are exactly the same as one another, image-quality-wise.

you should not expect any difference when moving from DVI to HDMI,

Because HDMI evolved from DVI, they are both identical when it comes to video.
