If you're in the US, you cant bring any items in for a repair inquiry. You have to email repairs. Email is on the website. If you're outside the US, not sure what they're doing, so check your own country's lv site.
As for the actual flaking, I would consider that a normal con for prints, even if you haven't really used it. The way animations, and other lv screen prints + paint, are done, is that the ink/paint is applied over the already treated canvas. LV canvas is pretreated to make it have PVC properties, and paints + ink flake off of plastic whether you use them, or hang them up as wall-art pieces. You can roughen up plastic for better hold, but inks and paints will never actually bond with the plastic. The environment has the greatest effect. Too humid and/or too dry will cause ink + paint to flake off faster. Flexible materials tend to not hold onto unbonded surface inks + paint as well. One year is extremely short lived though, if you don't use the piece often. Most likely the storage conditions weren't optimal, or too much ink/paint was used during the printing process.
LV may offer to fix it, or issue a refund/credit. Just something to keep in mind if you choose to get another animation piece.
