NO. IT IS NOT. If it is a backup, then you should be able to restore it verbatim without involving a middle man 3rd party

eSIM profiles are not backed up, as the key never leaves the Secure Element. What might be backed up is a token allowing the reissuance of a replacement eSIM by the carrier.

Can you prove it tho? Apple controls the whole hardware and software stack. They absolutely could store these keys in icloud backup.

Would be awfully obvious to have a subscriber to whom you issued an eSIM profile to an eUICC with the Removable flag set to False later accessing your network with a different IMEI...
