The question is, which live TV OTT services re-encode at which qualities? From a baseline of 720p30 (below broadcast transmission quality), various streaming services seem to have been upgrading to 720p60, or 1080p, for some content. Some of this seems to even exceed the broadcast transmission framerate?

There is a bigger difference in video frame rate between the services, but this feature really only impacts the clarity of sport streams because it minimizes motion blur.
DIRECTV NOW and PlayStation Vue have 60 fps on most tested channels; fuboTV has 60 fps on major sports networks.
Hulu Live TV, Sling TV, and YouTube TV stream at 30 fps [OUTDATED?]. Hulu and Sling announced higher frame rates for later this year.

...in time for the 2018 Winter Olympics and March Madness (NBC and Turner channels, respectively).
Phase1 60fps channels:
All SHOWTIME channels
All of our available NBC affiliates
About half of our available FOX affiliates
*individual FOX/NBC affiliates may temporarily revert back to a 30fps version in order to bring you the most stable playback stream.
Phase1 60fps devices:
Samsung Tizen TV
[NO ROKU YET]
For example, Hulu Live just started doing 60 frames/sec this month including local NBC, NBC Sports, CNN, TNT, etc. Does this mean NBC natively provides a progressive 60 frames/sec national feed, even if all NBC affiliates end up broadcasting at an interlaced 60 fields/sec (via OTA and traditional cable carriage)? Or is Hulu Live doing their own motion smoothing/interpolation beyond the native NBC feed?
I also assume that no OTT service actually streams with interlaced video, so for example YouTube TV deinterlaces any 1080i feed to provide a 1080p30 stream?
