Does Cox have HDR?

Yes they are.  I moved a set from my game room to the living room, where I previously had a 1080p plasma hooked up.  Maybe it'll just take a while to update or something.  I did go into settings on my box and change max resolution to 4k

The set does support HDR.  I just moved it from being always hooked up to an Xbox to the room where the cable box is.  And I did change settings on the box to 4k from 1080

This is like saying, "My wireless router supports encryption."  Okay...which standard:  WEP, WPA, WPA2, WPA3, etc?

I looked up Netflix and it supports Dolby Vision and HDR10.  If your TV doesn't support these industry standards, Netflix will probably send the dynamic range of the HD standard.

TV sets may also have a proprietary standard, which is a standard the manufacturer invented.  Probably not as good as the industry standards (HDR10, HDR10+, Dolby Vision, etc).

You had your cable-box connected to the soundbar?

Does you TV have an eARC port?

Yes and Yes.  It's all set up correctly now.  My Atmos soundbar can handle any signal I've thrown at it, but this one I'm just finding out can't.

All under the TV, huh?

No.  You have issues.

If you have one speaker beneath the screen of your TV, it's a "soundbar."  However, if the one soundbar is the hub for 5-11 speakers, it's a "soundbar system."

If you have a soundbar system, it may have better chipsets to decode the hi-def audio signal from your HD and UHD sources (Netflix, Prime, HBO, etc).

If your TV has an eARC port, connect the TV to the soundbar via eARC.  Via eARC, the TV is basically "hands off" with decoding audio.  The TV will separate the raw audio data and pass it to the soundbar for decoding, processing, steering, etc.

Because TV sets only provide 2-channel stereo, its audio processing stinks.  Let the component engineered to process audio process the audio...especially if it's heavier data.

I always said cable-boxes are the worst streamers.  If you want to stream like a pro, get a device engineered to stream.  Streaming apps on a cable-box were just an afterthought to dupe subscribers from cutting-the-cord.

Yes, wifi box.  Situation is resolved :)

Kewl deal!
