Plug & Play TV Sets for DirectTV Stream

In going about trying to get my client (who is a U-verse customer) set up with DirectTV Stream I was told that there were some TV brands that were "plug & play compatible", i.e. that if you got the right brand and model, that you could simply run a CAT6 patch cable from the network jack directly to the TV set and not worry about having to get a "streaming box". The rep mentioned Samsung but said he didn't know about any other brands and was vague on if it was limited to only certain models. Where can I find a comprehensive list of brands and model numbers of TVs that are directly (plug & play) compatible with DirecTV Stream, without having to use a set-top box? I'm not interested in any add-on devices like Amazon Fire, Roku Stick, etc, by the way. I want to go straight from the network jack to the TV via a patch cable and be able to access the various DirecTV Stream packages. Thanks!
