Secondary sheave questionable?

😕 Clutch and belt inspection. Found a number of what looks like cracks or maybe only blemishes on secondary. Should I be concerned? It's under warranty, would they bother replacing or say nope wait until it explodes?
Yes, I've seen pics of these broken. I've heard meah Sent it!


I am truly inquiring if I should work with dealer/warranty ASAP or does this actually seem typical and OK
