All up I found the first season kind of bland. I enjoyed the experience of watching it, but in hindsight it was not super memorable or interesting.
There's no confirmation that it will ever get a release on physical media, unfortunately.
Netflix shows usually make their way to home media.
Amazon shows usually don't.
There's no precedent for D+ so we just have to wait and see I suppose. I think it will come eventually, but not for a long time.
