The blade is genuine, that's how Butterfly's ALC looks like, the woven pattern is unique and no one else uses it.
The "softness" that is associated with these blades has an explanation, basically they use the minimum amount of resin possible. That is why you can see spaces between the individual threads. The downside to this is that it makes the blade less durable, delamination of the top ply is not uncommon and I've fixed a few. It was probably stored in an humid environment, or at least subjected to temperature changes. The shrinking of the rubbers might have helped that process, I'm betting that if you remove them, they will be a lot smaller.
