I just recently got into the 4K game and last night's NFL broadcast was the first one I've had a chance to compare to OTA. I have to agree that my local Fox OTA looked better, almost as sharp and the colors were much brighter.I thought the 4K was a little disappointing also. I was switching between the 4K feed, HD feed on NFL Network, and Network feed from my OTA adapter. The OTA feed seemed to look best to me.
