Nope. It's much more boring, but the best grow room wall covering is plain white paint or panda film (black one side, white the other, almost lightproof plastic film- buy from hydro shops, hardware). "Retired" real-estate signs, made from that plastic board resembling corrugated cardboard (brand names Coroplast, Corflute) makes a fantastic wall covering. Durable, sterilisable and cheap as chips.

Reflective materials like alfoil and mylar can inadvertently create focus points for light. Plain white diffuses light broadly while reflecting a very large portion back to the plants.
