That sounds like EGR soot.
How do you expect the fuel injectior cleaner to clean the upper intake when the fuel and fuel injectors are in the bottem of the intake next to the cylinder head. I have seen gas engines with everything south of the fuel injector almost perfectly clean, anything the gas touches gets very clean, so on almost every fuel injected engine the cylinder head intake port is nice and clean and on older TBI engines the entire intake track is clean.
My camaros carbureted intake is also very clean.
I don't see how any cleaner would work in a diesel since the fuel is directly injected into the combustion chamber and instantly incinerated.
The best engine cleaner I have ever found at least for a diesel is to run water injection.
