Digging is a bit tricky to explain even with pictures but basically it means that the little sort of triangular facets around the edge of the crown are more vertical than they need to be. This is usually done because the diameter of the diamond has been bumped up a little so that the finished circle of the diamond pokes out past the edge of the rough and hence is a little out of round, being dented or flat on one side. They place the triangle facets right over the dent and rotate them up so that the dent is sawed off into the little triangle.
You can also dig out the lower facets in the same way.
The net result is to shift some of the light return away from the top of the diamond and off to the sides.

Aren't you planning to go back there? See if you can tell them apart. You probably can't. I don't think GOG would buy a diamond for their platinum select inventory if it was not a great stone. They chose it, they wouldn't buy a bad stone.
So really we can't tell you what to do. I prefer H color over I color. I also like higher clarity. If I were to go smaller, it would be to get better clarity and not a thing to do with the ASET image of that stone. That is not a poor ASET image. If the clarity is totally eyeclean and you are okay with that, then I wouldn't switch stones unless they can show you a visible difference in edge brightness.

Ideally you should look at some I stones as you will likely be able to see tint under some real world conditions, and you should also look at some H & A versus just excellent cut stones. Of course every stone is unique and what you can see locally will not be a perfect match. Asking GOG for a video of this stone next to an I might be helpful but of course videos aren't perfect either. Definitely ask GOG what they think.

That's a the decision you have to make for yourself. There's going to be some sort of trade off so you have to find what is tolerable to you.
The ASET isn't terrible but I can see why some might not like the particular look of that diamond.
GOG has a vid that shows a painted compared to a conventional H&A. https://www.youtube.com/watch?v=7kmj-TkqTuI
