Android (phones, tv boxes) doesn't respect DHCPv6 IA_NA, but it should respect DHCPv6 IA_PD. Unless you have some other system that doesn't respect DHCP? Linuxes, Windowses, Playstation 5's support DHCPv6 IA_NA without problems.

But also, even if a device doens't support DHCPv6 IA_NA, you can always also have a DNS server in your network, and you can bind SLAAC-generated Android addresses to simple subdomains. This seems better than DHCP anyway.
