I didn’t see anything in the review addressing audio lag, if I missed it please let me know.

I’ve noticed huge amounts of audio lag in this TV. Using Arc it can be as high as 300ms, which is disturbingly out of sync. Internal audio is closer to 150ms. I’m not the only one to see this, and apparently this isn’t the first LG model to have this problem.

There is an inconsistency in measuring input lag and not audio lag: audio can be in adequate sync for cinema mode, but when video is sped up in game mode, if it leaves audio behind they are now very much out of sync. That’s what I think is going on here: audio is already lagging in regular viewing modes, but if the lag is less than 80ms it’s not too noticeable, so lipsync is passable. But when the video is accelerated by 100ms or so for game mode, the gap between them widens intolerably. This is a thing gaming consumers need to know, whether it means getting an external 4k receiver, or looking at another product.
