There may be a difference in color range as HDMI is typically used for TV, but you can change that in your graphic card settings.
Newer HDMI versions support higher bitrates which in turn allow higher colour depths (10 bit per colour) and HDR, so again can look better.
But for the same resolution, bit depth and so on, they will be identical. They are both digital signalling methods so the cable should not matter, but lower quality cables can cause noise and interference.

The cable has nothing to do with the picture quality, it's the interface and protocol over it.
DVI only supports 8-bit RGB colors, but it comes with single and dual link varieties.
HDMI supports faster speeds larger resolutions, up to 12-bit colors, and other colorspaces than RGB, but if your monitor or video card only supports say 1920x1200 at 60 Hz and 8-bit over HDMI, then that is the best you can get anyway and it does not matter if you use DVI or HDMI interface.
And, it depends on your monitor, if it allows for same resolutions to be used over HDMI and DVI. Some will, some won't, as DVI is primarily meant for computer monitor connection, and HDMI is primarily meant as a television connection.

Yes. Absolutely 100% yes. Powerpoint is a huge offender offering use of the full color palette range so when you toss two monitors viewing the same thing, one HDMI, one DVI, the DVI will loose color info sometimes if the source is not in the RGB range.
Seen it happen, big time.
