Even if kala ilan is only one color you still have that kasha on the gemara – maybe we just discovered a new min. So this is irrelevant to our discussion.

So you have to assume that rishonim knew about it and wrote that it was murex trunculus but didn’t wear it because of gezeiros and therefore it was forgotten and none of the acharonim ever saw the writings. If the shiltei giborim is the only one who says it and it’s a recently discovered manuscript then that would address the bais halevi. Is that the case?
