Anyone using YoutubeTv for World Cup?

I signed up for a 21 day trial (never used it before) to watch remaining games using the standard plan, watching on a fire stick 4k

• why is the quality so bad?? its all in 720p but looks far worse than the broadcast on tv! I dont even see an option for 1080p/4k
• is there a world cup hub where you can see/follow teams, replays etc? I see a bunch of fifa world cup live today entries from Fox
• there doesn't seem to be a easy way to see replays. I can't see replays from yesterday eg, only 2 days ago I just want a list of all completed matches
