Micro crack on new Cashion Icon BFS rod?

I just got a replacement Cashion Icon BFS rod from Tackle Warehouse (already paid $90 for a warranty replacement).

Before fishing, I noticed what looks like a micro crack on the blank, between the first and second guide from the reel. Hard to tell from pics, but concerned it could break or start to over time.

I’ve already reached out to Tackle Warehouse, but wondering, does this look like a real crack or just a cosmetic mark? Worth fishing or should I exchange it?
