I have no idea about those, but You Tube TV is in 1080P and Dolby Digital+.
Also, the majority of shows on Traditional Service are in 1080P/DD+ on the streaming services the next day, some shows are in 4K, FX shows are in 4K on Hulu, some Fox shows, some CBS shows are in 4K on Paramount+.
There are more, not enough time to check them all out.
The live TV streaming MVPDs like Sling and so forth can't broadcast in 4K because the networks don't deliver their feeds in 4K. Which if I had to bet will never happen.
