That is to say it is normal for any grey toned (neutral) image. A pure carbon on cotton rag (with no Optical Brightening Agent) print is not perfectly neutral because the paper is not nor is the 'black' of the carbon pigment. Nor do they need to be of course. That's not to denigrate how wonderful those can be but it is a silly irrelevance regarding the camera differences. Any file however developed can of course then be converted to monochrome.
