I was hoping someone would ask as I don’t know either. I’ve heard of Ambient Mode in the context of Samsung TVs, and I believe that was being moved under Art Mode, but I’ve no idea if that is what they are talking about.
Yes, they are moving it to the Art mode. But all the free part like my Photos are being removed, and they are putting it behind a pay wall so to use the functionality I bought the TV for in the first place I now have to subscribe.
