What level do you have your "center level" speakers set at? It's too late now but I would have suggested you try the system out with the factory firmware first, before updating the firmware. It has caused various issues for some.
I think my LG OLED65C7V is supposed to support Dolby Atmos (DD+/Lossy version) over ARC but it's not working using the built-in Netflix app and I've read numerous people having similar issues online.
I would loose out on HD-formats completely by going through the TV over ARC. With the Apple TV 4K connected directly to the soundbar I get Dolby True HD and DTS: Master Audio decoded into LPCM when using Infuse. This won't be possible over ARC as ARC does not support lossless formats at all, you'll need eARC and HDMI2.1 for this and that's only available on the newly announced LG 9-series for OLED's and the Samsung HW-N960 does not have eARC/HDMI2.1 so it wouldn't work even with support on the TV.
According to LG themselves both my LG OLED 6-series in the bedroom and my LG OLED 7-series in the living room are all limited to Dolby Digital (AC-3) and DTS.
If you playback anything in MPEG it will be decoded into PCM. If you playback Dolby Digital it will bitstream as Dolby Digital, if you playback Dolby Digital Plus (eAC-3) it will be decoded into Dolby Digital (AC-3) and not be kept as Dolby Digital Plus (eAC-3) and if I playback HE-AAC it will be decoded into Dolby Digital (AC-3). DTS will be bitstreaming as DTS or decoded into PCM depending on the amount of channels. DTS Express will be decoded into PCM. Dolby True HD will be decoded into Dolby Digital or PCM and DTS: Master Audio will be decoded into DTS or PCM.
This is when you select "Auto" mode for ARC. You can enforce "PCM Mode" which basically will decode everything into PCM and do no bitstreaming.
My LG OLED 6-series does not support Dolby Atmos over ARC, and my LG OLED 7-series supports it in it's lossy form (using Dolby Digital Plus + Atmos information as a part of Dolby MAT 2.0 or whatever they are calling it providing the regular DD+ soundtrack + Atmos metadata on-top for the soundbar to handle).
I don't think this has much to do with LG to be honest, these are all limitations of ARC which isn't all that great. This is why eARC is such a needed improvement, but sadly I won't replace my TV's any time soon so I won't be getting eARC for years to come. Getting a new soundbar with HDMI2.1 and eARC won't help me one bit as you need it supported in both ends.
I can't confirm or verify whether ARC/my LG OLED-TV is doing any kind of down-mixing when decoding from various formats such as Dolby Digital Plus into Dolby Digital, Dolby True HD into PCM, DTS: MA into PCM etc.. As I have yet to test it much and there is no real indication on the Samsung HW-N960 telling me the amount of channels that is being fed over LPCM and PCM. When getting audio over LPCM or PCM it doesn't really tell you anything at all.
This is why I prefer to have both my Apple TV 4K and my Xbox One X connected directly as this will ensure that I can get the full LPCM 7.1 when playing back Dolby True HD or DTS: Master Audio within Infuse on my Apple TV 4K or when playing back anything that supports Dolby True HD or lossless Dolby Atmos on the Xbox One X it won't be lost due to the limitations of ARC.

You have a more advanced EQ within the app. You can also access this directly on the soundbar by holding down the settings-icon for 5 seconds. But it's really hard, if not impossible to resemble DRC (Dynamic Range Compression) using a EQ meters. DRC is supposed to compress the dynamic range across the board which is well suited for lower volume levels at it helps you reaching deep and high even when your lower decibel would otherwise restrict/limit you from reaching these dynamics in the sound-field.
EQ only lets you alter various frequencies responses, so you can increase or degrees various portion of the sound signature to accommodate your preferences. But it won't compress the dynamic range to be more suited for your volume levels.
What's strange to me is how the Samsung HW-K950/960 had several levels of DRC which you can activate, while the Samsung HW-N950/960 lack these options entirely.
