According to reviews, the near-black performance on less than pristine material for the LG OLEDs is inferior to the Sonys and probably the Panasonics as well. While I can confirm the LG looks awesome for near-blacks on excellent feeds, it's well documented that for lower resolution and lower quality near-black content, sometimes the LGs just don't do so well. I'm not sure what you are showing is exactly the same, but it's probably for the same reason. The Alpha 9 just isn't quite there yet. In addition, I've noticed that the motion handling of the Alpha 9 is just not top tier.
OTOH, the Sonys have a too aggressive ABL and they also clip all HDR highlights above 1000 nits, where as LGs tone map to bring out all that extra detail while still maintaining overall brightness. Then there are the Panasonics which don't support Dolby Vision at all. (They aren't available in the US, but they are available here in Canada.)
So... so far, there is no perfect OLED.
I've said before that what I am hoping for is that in four years is an LG SoC that can handle motion and near-black content as well as the Sony does now, but while retaining or improving the brightness advantage, at a lower price and with HDMI 2.1.

It’s the Netflix sound loss for 1 sec every 3-4 min when watching Dolby Vision + Atmos series .
On my Marantz receiver, the TV says I'm getting Atmos, but I don't actually get Atmos. I get Dolby Digital Plus 5.1. Plus it seemed to cause inconsistent problems over ARC. So I've since shut off Atmos and stick with DD+5.1 only. That seems to be working solidly, and it's an improvement over the DD5.1 of optical.
