Thank you With your help and advices everything works fine !
However I would made a suggestion about GUI interface when configuring IPv6.
Mode "DHCPv6 with Prefix Delegation"
>>> This mode enable the use of dhcp6c (it run the command dhcp6c -c /tmp/dhcp6c.conf -T LL #WanInterface).
So it is meaningful to propose the option "Dhcp6c custom"
But with the mode "Native IPv6 from ISP"
>>> From what I have observed : No use of dhcp6c. Even if you enabled the option "Dhcp6c custom" with custom code.
So why not hide/remove the option "Dhcp6c custom" when the mode "Native IPv6 from ISP" is selected ?
Static DNS 1 & Static DNS 2 --> Any IPv6 DNS Servers (free or Google or ....)
Assigned / Routed Prefix -> Freebox prefix delegation but not the 1st one, 2nd prefix used (don't try to use the first one due to warning message).
Ok. I've read your exchange with Per Yngve Berg regarding this setting, but I've not really understand the explanation

Ok. It took me a bit of time to understand, but it looks like you're talking about the IPv6 Scope:Link address of the DD-WRT router that we can get via the ifconfig command.
At last, you did not answer this point, but I confirm we can disable Radvd when we use Dnsmasq. It works fine.
Overall, after applying all those settings, everything works!
DD-WRT, Windows clients and the Apple TV all get their IPv6 address and TV lives now works fine on the Oqee app on Apple TV.
