Given their size, they would lack the power to launch feathers as if pretending to be Gilgamesh using Gate of Babylon. Not to mention, by your reasoning they should be shooting feathers all the time. If they were organic entities, maybe the size and energy requirements would cause problems; but they're not organic, and as such the square-cube law as it applies to biological creatures does not apply.

As for not launching feathers all the time; they exist to kill people, and whether by instinct or an extremely low level of concious thought they only use their feather attack when they need to do so.

Now, the camoflage thing: Chameleons actually don't blend with the environment that well, they mostly adjust colors based on the weather and their mood, or for communication. They do it with a combination of pigment and a crystaline lattice which changes colors when excited.

If you want an animal which DOES camoflage itself, the better choice would be the mimic octopus or cuttlefish. the cuttlefish uses chromatophores (and a couple other things i can't remember the names of right now) to change colors on a microscopic level. they adjust these cells using hundreds of muscle fibers which expand and contract them, altering how light is reflected.

Grimm, simply put, don't have pigmentation, or the biological functions necesarry for camoflage.
