I can see the appeal—iridescence can throw off a shooter’s eye, but it also gives away movement and position. On a plain backdrop it might work as a decoy, but in a real engagement it’s more trouble than it’s worth. Stick with matte, low‑reflective fabrics unless you’re doing a staged shoot and can control lighting. If you’re going to risk it, treat it like a tactical decoy and keep the rest of your gear as dark and subdued.
