It would be nice if additional colours would be supported, à la Hexachrome by Pantone (this was a 6-colour ink system which covered more than half of the PANTONE spot ink colour space and made quite vivid photo reproduction possible).
Even better would be a mechanism like to Cerilica's Truism which would allow one to use arbitrary filaments and preview how they will blend when printed.

primed3d can do photos onto models. still limited by print resolution, but very cool concept.
Photo reproduction should be the target here...
And it looks like the software support needs work too - the obvious way to do it is being done able to import a jpeg or png to project or wrap onto the surface, a bit like texture maps in video games.
They’re not limiting you, the community work this is based on doesn’t either. Yeah they’re going to sell sets for easy use but it’s just color mixing. If you know the filament colors, which is what the filament database is for, you’ve got all the info you need.
And you’re only limited in quantity by how many filaments you can load at once. A full INDX setup on a Core One is 8. I thought you could daisy chain Bambu AMS units on their printers, which would let you get your 16 maybe? I’m not very familiar with their offerings.
