Hopefully there will be a fix for AC4 support in Kodi once we get some true 4K broadcasts later in the year.
You're going to be waiting a lot longer than a year for both of those things. Kodi won't get official AC4 support until it hits a stable version of ffmpeg and they upgrade the version they use to it. At this rate, support will never land in the current version Matrix/v19, and likely won't make it into the next major release of Kodi v20. There are some ways to create an unofficial Kodi build with the AC-4 patches out there, but it involves editing the compilation scripts and the AC-4 patches so they work with the version of FFmpeg Kodi uses. With Android it's even more complicated because of apk signing, so you have to uninstall your current Kodi installation on the Shield, compile a self-signed apk and install it, redo any custom settings you made and reinstall and reconfigure all of your add-ons. You'll also have to compile any future updates so the apk still matches your self-signed signature. FFmpeg also doesn't currently support interlaced HEVC, so on Kodi you'll see some weird issues with KIRO and KUNS where you only get a 1920x540 image stretched to 16:9.
4K isn't coming anytime soon because they have to share the ATSC 3.0 signals for at least 5 years so no one loses access to existing programming, so there isn't enough spare bandwidth for 4K when the ATSC 3.0 lighthouses need to carry multiple HD channels. (i.e. KONG, KCPQ, KING and KZJO are all sharing KONG's RF 31 signal, and KOMO, KIRO and KUNS are all sharing KUNS's RF 24 signal) The lack of bandwidth is also why most ATSC 3.0 stations aren't carrying HEVC versions of their subchannels (TBD, Stadium, ThisTV, Bounce, etc), and instead have special temporary authority to only offer them in ATSC 1.0.
