4K picture quality vs Regular broadcast channel

I have a Samsung 4K UHD TV with the X-1 4K box and the picture on the 4K channel is washed out and void of any real color compared to the regular broadcast channel. This happens to be a FOX broadcast but it happens when NBC or anyone else is broadcasting. The regular broadcast channel is always a better overall picture. 

See pictures attached.   These were quick photos because I wanted to try and get the same shot. The difference is actually glaring. 

Anyone else having these issues?

Thanks
