Hopefully Sound & Vision does a comprehensive review on the SL10.
There has been an astounding number of complaints about Dolby Atmos and the 'Movie' preset sound mode performance with respect to their prior SK10Y model release. During highly active or dynamic sound events, dialog gets squashed and shoved into the back of the sound field. LG released a firmware patch and update to their mobile app which introduced a 'Center Channel' control. Unfortunately, object oriented sound decoding doesn't work on a basis of center - left - and right - channel levels and if one is to follow the prescribed remedy (by LG) to jack the center level up to a max of 6, it doesn't help the Atmos dialog presentation by any appreciable amount and it introduces obvious issues outside of dedicated Atmos playback. There is a wealth of Atmos material that demonstrates the issue with the SK10Y - 'Game of Thrones' being a prime example for A B testing. Any of the battle field scenes show just how poorly the dialog objects are treated amidst the entire soundscape in Atmos mode. Equally, there are a number of "super hero" movies that also employ Atmos and are great demonstration sources. This DSP handling issue can also be forced with the programmed 'Movie' mode - one of the built-in DSP sound field presets available on the SK10 - that also creates significant attenuation in dialog content when used on non-Atmos audio that encompasses complex sound fields. All of this points to some serious DSP shortcomings.
The SK10Y is sort of 'water under the bridge' now - with the announcement of these new models at CES. But little to no professional attention from sites such as this one or other professional review venues have given the SK10Y the critical attention it sorely needed regarding dialog performance.
****************
Hopefully Sound & Vision gets it hands on a SL10 and thoroughly reports on the Atmos and matrix 'Movie' modes in this regard.
It's a key area of review and everyone should agree that dialog handling is probably one of - if not the - most important metric of a high dollar sound bar system.
