It's carbon migration from the forging process. When using high heats as for the forgewelding some of this will happen. Superficial carbon content from the edge steel will move over into the iron.
It can be difficult to say if it's too much or bad just by pics, as it's width will depend on angle of the grinding. If the knife works well, don't worry about it.

did you talk about the cloud above the welding line or about the "weak" welding line ?

I see a lot of Katos with a black line like that at the juncture of cladding and core steels. And it can be felt with the fingernail in some instances.
