I smell like a Christmas pudding
That seems fair as every brush manufacturer has different batches of knots which vary in quality. Some document them so you can be sure of which batch your are buying but Simpson I believe do not. I would expect the tips to soften slightly over time but the hair shafts to retain their backbone, there may be a slight knot loosening but little in the way of bloom in my experience. My advice is to use the brush heavily until you are satisfied and if you remain unhappy then you can return the brush for replacement with one year of purchase.
