Good day to all you gentleman

I have recently upgraded to a silvertip brush from Frank Shaving, it is a 21mm knot and I find it quite soft which is just perfect. Although, I have seen a bit of a change in the brush since the first lathering, which I shall point out in pictures by the end of the post. Also, I am having some trouble adjusting with the silvertip, as I am not familiar with the silvertip technique, it produces a nice and creamy lather but the amount produced is significantly less than the on produced by the boar with the same amount of cream, which I am sure is supposed to be the other way round and I am supposed to get more lather than the boar. I don't think it is the brush, I find its floppiness texture just perfect and it feels good to the face, it must definitely be my technique and I would appreciate all help and suggestions.

Here are pictures when I received the brush and after the first lathering. Is the change normal?

I dont have a picture of the brush when I received it so here it is as portrayed by the seller, the brush looked exactly the same when it arrived.

And here it is after the first lathering, it has stayed such since then

I am just curious about this particular matter of change not paranoid, should I be paranoid?

Again, I would be grateful for any and all the help
