I cannot speak for the LG display, but Roku continues to support IR codes, even for their devices that include RF remotes. I have the latest Roku Ultra with Dolby Vision support, and it works fine with my Harmony 650. I did not have to do any re-programming of the remote when I swapped the new Roku with my old Ultra.Another problem is manufacturers having been moving away from IR remotes - My LG TVs and Roku use RF so I've been making due with juggling three remotes without too much problems.
