mrdiscreet918 I think the summary currently is:
1) Passthrough doesnt work. Won't work until apple allows it (maybe never)
2) While watchable, video quality still suffers if you play directly via the website. The colors are not perfect, there's a frame rate issue and the player itself doesn't work very well. Better just download the video's you like and stream them via either DLNA or a windows share to your AVP with for example Moon player. Quality then simply is the best out there, nothing beats the AVP at this moment (and I think it will take a while before a competitor beats it). It's just crazy good. Personally I crank up the contrast in moonplayer VERY slightly and it looks even better. Your question was related to specific content though, so my 'answer' is not directly directed at you but more to anyone wondering what the current state is of the AVP+SLR.
Let's hope apple announces PT capability tomorrow at the WWDC 2024 conference but I honestly doubt it will ever become available...
