When Apple TV 4K is connected into the node, it is not getting the maximum download speeds. Below I have tested the following network topographies that troubleshoot that something is going on where the node is decreasing the download speed of the Apple TV 4K.. All wires have been tested and that is not suppressing the speeds.
 

Network topography:

Be550 - Be550 - Apple TV 4K =approx 120 Mbps download

BE550 - switch - Apple TV 4K =approx 950 Mbps

I'm thinking somehow the firmware is suppressing the download speeds on the node for the Apple TV 4K. I have factory reset the nodes that has not resolved the issue. As I said, before, the wires have been tested and the same wire that was used to connect from the node to the Apple TV 4K was the same wire used to go from the switch to the Apple TV 4K. So I'm not sure why there's suppression of the download speeds. Can someone please help ?
