Hi,
I understand you are using ConfigMgr in combination with DO. Looks like your peer-to-peer over port 7680 TCP/UDP is working properly.
1) delta download should be enabled in ConfigMgr client settings; this is local port 8005. See ConfigMgr console > Administration > Client Settings > Default client Settings > Software Updates > 'Ports that clients use to receive delta content = 8005' (details: Https://docs.microsoft.com/en-us/mem/configmgr/sum/deploy-use/optimize-windows-10-update-delivery#bk...)
2) There is also a parameter for DO to help it avoid to fall back too quickly to CDN: see https://docs.microsoft.com/en-us/windows/deployment/update/waas-delivery-optimization-reference#dela.... We set it to 1 hour.
3) You can also check DO logs on client which gives very clear and detailed info: Get-DeliveryOptimizationLog | select Message -Last 250 | Out-GridView
Hope this helps.
Johan

For other Admins stucked on the same situation....
Check if your global domain GPOs are set to IGNORE your local/default/built-in firewall rules.
Keep in mind DO firewall rules are created and active by default for any W10 edition.
