That's interesting. I didn't know that. I thought that if you select the dice rolls seed generation method, that the entropy comes only from that source. But according to the documentation you linked to, 256 bits of entropy is already generated from Coldcard's hardware and the dice rolls are an addition on too of that.
Coldcard provides all three options - PRNG only, PRNG + dice, or dice only.

You can verify this yourself by going to Ian Coleman, showing entropy, putting in "5", choosing dice rolls, choosing 24 words, choosing BIP 84, and generating the same addresses as OP:
