MovieFan: Amazon use to limit what Plex is allowed to support. Yeah, that’s what I figured. The VegaOS devices started coming out and they supposedly supported the full quality on commercial streaming services (so, at least 25 Mbps of HEVC, 4K res, HDR, EAC3 audio…) yet when the Plex app shows up for it it’s limited to pauper bitrates of 1080p and only AAC audio.
