Thanks for feedback! I thought that the Pi3+ had a limitation with Dolby Atmos TrueHD! So following your feedback would this solution be a better value and still achieve unadulterated 4K Dolby Vision + Dolby Atmos TrueHD using directplay If a Blu-ray Disc can do it, a harddrive can do it………. Remember, all your doing is reading a file and playing it. It’s sort of not super well defined right now, it’s all a cluster. You would want to likely use mp4, but again, need to do your homework on what file type is best for DV/Atmos. I am not smart enough of how ripping and codecs work to explain why, but I know there is loss. Will it be “noticeable”? Maybe? But no codec will preserve the same detail and data as the original bluray. Nothing will look as good as directly playing from bluray. Nvidia shield pro is the best option, hands down. It takes effectively no power to direct play. The pi would be fine for direct play of any file. Is the Shield noticeably faster than the LG CX?

Would i need to upgrade NAS SSD for cache or fine as is? How is power consumption, cooling and noise from the NAS? What file format would i need to have the video files in to achieve this? Would there be any discernable difference in playback quality vs just using my 4K blu ray player (Panasonic UB450)?

Would this setup be capable of direct play 4K Dolby Vision + Dolby Atmos TrueHD/DTS:X as well as transoding 1080p? What I'm thinking to do is to get the Nvidia Shield Pro to use as the client (connected to 1Gb router via ethernet) then hook it up to my AVR via HDMI and to also buy a NAS (Synology DS920+ most likely and also connect to router with ethernet) and setup the NAS as the Plex server using my 2 existing WD Black 4TB HDD's but there would be no wired connection between the NAS and Shield. I'm currently using a raspberry pi3+ as a plex server and the WebOS plex client on the LG CX to direct play backups of my dvds but considering improving the setup so can i backup my 4K UHD blu ray discs then direct play the full fat files (atmos TrueHD and all) but understand that the pi wouldn't be capable plus the LG CX is a bit slow with Plex client.
