From the Private Information section of the rules, the contents of Markers is private information. However, the Camo Markers themselves have mimetism values and are implied to be open information (as the camo rules themselves call out this fact). This, in effect, seems to disable the ability that a TO unit in N3 had: which was to "fake" being a regular camo unit by downgrading the camo. I don't see a way to do this in N4. Is this an intentional change?
If you look at the Camo marker rules, they’re explicit about making the level of Mimetism the trooper (or whatever) possesses public information. And there’s no more leveled skill to switch between. So it sure looks like “downgrading camo” is no longer a thing.
Yeah it's an unfortunate nerf but it does seem to be the case. My Hac Tao and Ninjas deployed as camo far more than they used Hidden Deployment in N3.
