It shouldn't make a difference. The Ultra only has 100Mbit Ethernet, as it's designed for Internet streaming, where even 4K maxes out around 25Mbit.
Thanks for the reply. I was expecting there was no benefit to the upgraded wire for the reasons you state. Was looking for the confirmation. But since the cost for the Cat 6 wire is just a few $ more than 5e, that is what I plan to pull for the dedicated drop to the Roku. Never know what the future may bring.
Nothing wrong with Cat6 for a permanent run, and generally recommended. I was just thinking it was about a short run like wall to device.
Just be a bit careful about going too cheap. The longer the run, the better quality cable you need, not just Cat type.
