True.
Chameleoid ability would be useful in wooded areas and such.
Light bending or dimensional phase shifting would be best used elsewhere.
The same rules for hiding, even with special camouflage abilities, would still apply.
Avoid being backlit. Stay in shadows. Move slowly if at all.
A negative aspect of such a "gift" would be that if you were called upon to defend yourself, it would have to be without weapons, as the uniform of the natural chameleon has no pockets.
