TV mounting advice for corner niche

Hi, I need advice how to mount a 77" (76 lbs) tv to this corner wall which has a 5x5x5 recessed hole. Ideally still want a small hole (hidden behind my tv) so I keep my router/cable box and other stuff hidden. I've done a lot of research and the best solution was to build out an inner frame and put it in the hole and attach to the tv to this (See photo link at the bottom). For more structural support I was going to attach a 3/4 inch plywood sheet to the bottom half. I would also use a full motion mount so I can access the stuff behind the frame. However, my AI bot consultant says not having a plywood sheet covering the whole frame is an extremely bad idea and is unsafe. I'm new to this new DIY world so any advice (weather it's disagreeing with the AI bot or other solutions) is appreciated. Here's are pictures of the corner niche and my mock up frame: https://imgur.com/a/yia4eYp submitted by /u/superdaveca [link] [comments]
