With a VPN enabled and the leak blocking toggle enabled, try using the extended test at https://www.dnsleaktest.com/ on GrapheneOS vs. any other variant of Android while repeatedly causing the VPN to disconnect by changing servers, toggling off mobile data / Wi-Fi and turning them back on, etc. You should see DNS leaks outside GrapheneOS.

We're still working on eliminating any possibility of accessing VPN provided DNS servers outside of the VPN tunnel without breaking compatibility.
