That niche is filled pretty nicely by Heidelberg. Their printers come with their own color correction and matching system. Plus they ship ICC profiles for accurate screen preview.
I was looking at Heidelberg since you suggested it. But, their product catalog is barely visible outside of spare parts and inks. The few things I could see, I cannot use them in a print shop, their equipment is much larger than the current print equipment which is nearing end of life.
