Wife handles our Netflix subscription and I honestly don't know if we get Netflix 4K. If that requires an upgrade tier I don't think we have it.
I was complaining about tearing and pixelated TV images a couple months ago. That's when Comcast swapped out our aging Cable Boxes for their Xi6 which doesn't require the coax - I think they call it IPTV as it all comes through internet. These new boxes support 4K UHD HDR so I am only recently discovering this feature.
We get over-the-air HDTV (1080P) via outdoor antenna on the basement TV but it doesn't have the newer ATSC 3.0 tuner which is required for OTA 4K.... and I'm not sure which stations if any in our area are transmitting 4K. There might be a couple but I -think- they reserve 4K for special shows or events but I'm not certain about this.
