There are many ways to make MGIV matte sing. It comes down to toning, for the most part.
If you print your highlights down a lot from pure paper white, you can get a lot of mood in the paper depending on how much you bleach. I like to use a 1:100 dilution of potferri + bromide and bleach for about a minute to two minutes, and then use either Kodak Sepia II, Kodak Sepia, or Moersch MT-3 to get a warm golden tone to the highlights. After I use Harman selenium toner, warm and concentrated, which further warms the highlights and really impacts the shadows to become both deeper and warmer. It honestly looks like a warmtone print once it's done.
But you can also use selenium toner first, and depending on how long you leave it in, you can protect the print from shadows up into the low to high mid-tones, and then when you bleach your bleach is incapable of bleaching the silver selenide, and only gets the very highest highlights. This gives a much more subtle effect.
Then you can leave your prints a bit lighter in the highlights, with just a hair more density in them than paper white. Especially if you edge burn your print, this is a really great technique with this paper, because the slightly darker edges still carry nice density post toning, but the parts of the highlights that are almost paper white look like they have an inner glow. It's hard to explain, but you get really brilliant tonality this way. Same bleach, and take the very lightest highlights back to where you're almost at paper white in the very brightest parts, and then when you re-develop the paper in the sulfide toner, you get this intensity to the highlights that can be so utterly beautiful for some subject matter.
I agree with Bob that the MGIV isn't very exciting on its own, but once you start to play with the toners, you can get really deep blacks, and highlights that don't look dull, but rather glowing, alive, and full of texture. If you're really good with it you can get almost charcoal black.
You have to try to experiment for yourself a little bit, play around with different bleach dilutions, and work your results until you like what you see.
I have attached two examples here. One a bit darker, and another a bit brighter, to give you an idea of what I'm talking about.
