I would doubt very seriously that there is a Sony 4k TV in the Cherokee 264ck.
There is only a few TV's that are DirecTV tuner ready, mostly the high end 60 inch or larger, that have a built in tuner per say. What they actual do is... you would still need the Genie box, then the TV connects to it via ethernet or WiFi. Then it would stream the box channels and DVR to the TV!
Some years ago DirecTV and TV manufacturers tried installing built in tuners, but they were limited... No DVR and such. Plus the updates DirecTV does are for their boxes, so a lot of consumers with those TV's were left in the dark!
All TV's now have an HDMI input so you could connect a DirecTV HD box to it, so in that aspect yes it is DirecTV ready
