4k uhd is terrible

4k uhd MLB games are terrible on the comcast xfinity set top box. When i watch the same game on an apple tv 4k or a firestick 4k the colors are much more vibrant and video quality is impeccable. Why is comcast xfinity 4k broadcast so bad?!?!

the 2022 world cup is next month and i have no idea how I’m going to justify paying what i pay for 4k box when you cant even show a slow moving baseball game with vibrant colors and 60fps. 

i know it’s not only me. There are plenty of other posts on this forum along with all of my friends in group chats confirming how washed out the colors are on comcast xfinity 4k.
