No problem at all. My JU7100 is a '14 model, and until I replaced that Roku with a Shield it worked fine. I only replaced the Roku because I wanted lossless audio bitstreaming on that TV. In reality, as long as the TV supports 1080p over HDMI, there's no reason for any Roku player would not work. While Roku players also support 720p, there have been reports of problems with TVs that support 720p and 1080i (not 1080p). But almost anything from the last decade will likely be fine.
I have a smaller Vizio 1080p TV that I use as a secondary computer monitor, and occasionally plug my Premiere into it so it gets updates, and it works fine there as well. HDMI is an industry standard, so as long as the TV is compliant, there should be no issue with any Roku player.
Dan Roku Stick (3600), Ultra (4640), Ultra (4670), Ultra (4800), Premiere (3920), Insignia 720p Roku TV, Sharp 4K Roku TV, Nvidia Shield, Windows 10 Pro x64 running Serviio and Plex on a wired Gigabit network.
