Hi, I'm hoping soon to get myself an LG C9 OLED to replace my long serving Panasonic 50ST60 plasma and I'm thinking about how best to connect it up to my existing A/V setup. I have a Yamaha RX-583 receiver and currently I have all my devices (Virgin V6 box, Xbox One S, HTPC and Nintendo Switch) connected directly to the receiver and then just a single hdmi cable up to the TV. Although my current TV does have some smart features I don't use any of them and just play everything through the various devices with the vast majority being done through the XBox, i.e. Netflix, Amazon Video, iPlayer, Plex, Youtube. This makes the setup nice and neat with fewer cables going to the TV and nice and simple to operate for the rest of my family who don't seem to care about gadgets as much as I do 
With the C9 having much more advanced smart features and built in apps for all of those services will using them give any advantage in terms of picture or sound quality over sticking with my current setup? I know the receiver supports Atmos and plenty of HDR formats and so should be fine to pass them through from the XBox but I presume I won't be able to use the VRR unless I directly connect the XBox to the TV and use ARC to send the audio back to the receiver? Are there any services where the XBox app is more limited than the built in version?
Are there any other tips about connection setup I should be aware of?
Many Thanks

As they are used to using the XBox I'm fine with carrying on with that rather than using the tv apps but only if I don't lose out on quality in terms of video or audio formats. From some google research it looks like all the big streaming apps on the XBox do support the same range of HDR and audio formats as the native apps so I think I will go that route for the moment at least. I don't really game that much on the XBox and as it's only an S rather than an X I don't think missing out on VRR is too big a problem at the moment. Maybe next year if I upgrade to the next gen Xbox and get a new receiver that supports eARC then I might rewire.
