The EBU made compelling reasons why 720p would be better than 1080i for HD

However 1080 is bigger than 720, so most sources are interlaced.

4K at least got ride of interlaced as an option, so 2160 is always progressive.

Unfortunately, no. The highest quality broadcast I get on ATSC is 1080i (the i=interlaced)

Even ATSC3.0 supports interlaced HEVC, from what I've read many HEVC decoders not designed for ASTC 3.0 struggle with it

Meanwhile games are dabbling with rendering interlaced (or checkerboard) + reconstruction pass
