I think I've seen the same thing. I use Verizon in SF for both an iPhone and for their 5G home internet service, so I've got some basis for comparison. During the setup for the home internet, they were very particular about where to place the device for line of sight to the tower. It consistently gets 1Gbps down and 300Mbps when in 5G UWB mode. There are rare situations in which it falls back an LTE connection that is somehow unimaginably worse than phone tethering. On the other hand, when I'm using my phone, it'll sometimes _think_ it has the ability to do ultra wideband, but it doesn't work, and the icon disappears and suddenly I'm back on ordinary 5G again with a bit of a hiccup that you note. If I ensure that my phone has clear line of sight to the base station, and confirm that it is using UWB, then I can get similar speeds and latency to the 5G home internet device. The ultra wideband mode is very sensitive to where you are in relation to the base station, so on a phone moving around your house it may be inconvenient or frustrating to have your phone attempt to use it.
