LG SK9Y big cons is only have one HDMI-IN, so you need to choose either one from your device.
- PS4 Pro or TV Box.

Decide which one can give you more movies in lossless audio (Dolby Atmos, Dolby TrueHD, Multi-channel PCM).

2nd throw away optical in, optical only can pass thru lossy audio and you won't need it.

Assume as you said PS4 Pro only up to lossy audio support.
But I think PS4 Pro support lossless track in Blu-ray, for local downloadable content wise I no idea.

I suggest below connection if you don't have a lot blu-ray and PS4 Pro support local downloadable content is not good.

1) TV Box to LG SK9Y HDMI-IN (for lossless audio)
2) PS4 Pro to TV HDMI-IN (for lossy audio)
3) TV to LG SK9Y HDMI ARC (for lossy audio)

As for 4K HDR, don't worry, it is fully support in LG SK9Y HDMI-IN and HDMI ARC.

Just remember,

SoundBar HDMI-IN give you lossless audio track as long your device connected to it support.
SoundBar HDMI ARC give you lossy audio track and may have sound delay issue.

A lot TV have Dolby Digital. You can get Dolby Digital by connecting your TV to SoundBar HDMI ARC, your Netflix can playback in Dolby Digital.

Some TV also have Dolby Atmos in Dolby Digital Plus, example LG OLED TV and by connecting to SoundBar HDMI ARC, your Netflix can playback in Dolby Atmos in Dolby Digital Plus, as Dolby Digital Plus still is lossy track where still capable pas thru HDMI ARC. ** Maybe this connection is not correct for LG TV because this SoundBar have a special connection type call LG TV and I don't have LG TV, thus I no idea what is the special of LG TV connection type.

The Netflix able to playback in above mentioned support track also depends on the Netflix apps in your device support or not as well.

To get sound format you need, it needs to be both side support.

Beside this, If the device can decode and output as multi-channel PCM, you get the exact same audio track (up to Dolby TrueHD and DTS HD MA) even though this SoundBar not support DTS HD MA, but due to the device you connected to the SoundBar HDMI-IN is support decode to Multi-channel PCM first before it pass thru to this SoundBar. In the SoundBar will display as PCM.

Decode to Multi-Channel PCM not included Dolby Atmos or DTS: X because this both new format is just a metadata on top of the Audio Track (either it is Dolby Digital Plus (only Netflix and iTunes movie use this format) Dolby TrueHD or DTS HD MA) The track itself either Dolby Digital Plus, Dolby TrueHD or DTS HD MA is decode to multi-channel PCM but not the metadata of Dolby Atmos or DTS: X. Also remember it depends on the apps itself capable or not.

Currently for Netflix & iTunes movies in Dolby Atmos at Dolby Digital Plus only support in Apple TV 4K Box. Since it is Dolby Digital Plus which is lossy track, so lossless track of Dolby TrueHD or DTS HD MA or Multi-Channel PCM is possible better.

So far I know for TV box only Apple TV 4K support Netflix in Dolby Atmos if the title support it.

Apple TV 4K origin support up to Dolby Atmos in Dolby Digital Plus up to 7.1 channel but not Dolby Atmos in Dolby TrueHD. For third party apps it is supporting auto decoded up to 7.1 channel Dolby TrueHD and also up to 7.1 channel of DTS-HD MA to up to 7.1 multi channel PCM. The sound will output as Multi channel PCM which will be identical with original track without any changes. The limitation is currently it can't decode the metadata from Dolby Atmos in Dolby TrueHD and also metadata from DTS:X in DTS-HD MA. This probably need more license and unless Apple support it else it is not possible third party apps support it and I doubt Apple will support for the moment since Apple own iTunes movies and also Netflix is only up to Dolby Atmos in 7.1 channel Dolby Digital Plus.

Dolby is a company. Dolby Atmos is one of the sound technology release by Dolby. They is plenty format had been release since year 1965.

Dolby is start as a company introduce noise reduction. The first consumer product is Dolby-NR introduce in cassette. If you have play cassette album before, you probably had seen and use before Dolby-NR device to reduce the noise generate by the cassette. I still remember it is such an awesome experience that time when first time I own and heard the cassette with Dolby-NR support Walkman - Panasonic Portable Cassette Player RQ-S33.

I suggest you study more by Google or at least look below few article for more understand and familiar with it.

Lastly for your information, it is call Dolby not Dobly.

No one will said Dolby only. Please read carefully the specification. They clearly mentioned DTS 2.0+ Digital Out, Dolby Digital Plus.

For Netflix support in Dolby Atmos, Netflix site had listing, only Apple TV 4K box support for TV box.

Wow! This look freaking awesome! I hope some day Nakamichi is coming to Malaysia. It always have wonderful design and price reasonable than any on the market.

Take for example this unit after conversion only RM 5.7k but you get 2 subwoofer, 4 rear speaker and 1 soundbar with every format in market support.

Normal won't be that much also. Many items sell locally even cheaper than overseas.

Yup agree. Without direct office also possible no warranty.

Assembly at where important? Important is how the quality control.

I know. I never care make at where one. Haha!

I can't answer you as I don't own Dolby Vision TV, it is pass thru as HDR to me.

But this is LG, LG always support Dolby Vision, I don't think it got issue on that, some more official document already mentioned support, nothing to worried about it.

Wonder this Q-Symphony did better or worst as they use specific Samsung TV speakers and join with the soundbar where TV speakers act as additional surround speaker.

Manual adjust each time is the only solution. Actually all sound is kind of equal on louder except Netflix, Netflix is much softer and it is like that always.

Nothing can do about this unless Netflix decide to tune it louder same as others.

This is nothing to do with SoundBar, this is Netflix issue.
