Ok, I bit the bullet again and bought two of the highest rated 8K, 48Gbps cables I could get. And they are not all that expansive either. Even though I only needed 3 ft from the Hopper to the Denon, these only come in two lengths, 6.5 and 10 feet. I replaced both from the Hopper to the Denon and then from the Denon Master HDMI out to the input eARC on my Sony A9G.
Watching BlueJays/Bulldogs basketball right now, perfect picture. No complaining about the receiver has detected....
So if you don't want to bother with the channel down bypass (not sure if it also bypasses the full 4K experience, I swear this is clearer than when I watched the NFL games) you can spend about $40 bucks and get the right cables. I needed 10 feet to get from the Denon to the TV, but if yours is closer two 6.5 footers would do it. Remember, you need to replace the entire transfer path. Hopper to your AVR, AVR to the TV.
Just an FYI,
