Theoretically its supposed to work. Practically, this is the first HDMI 2.1 source. It works with 48gbps LG TVs, doesnt work with 40gbps one. Like I said in the earlier post, hopefully the two companies work together to figure it out. For whatever reason, both LG and Samsung have decided to limit their HDMI 2.1 to 40gbps.
Edit:
Here's a quote from the NVidia reddit thread:
"Only the LG OLED CX model suffers from subsampling 4:4:4 to 4:2:2 at every resolution and framerate except 4k 60Hz, 1440p and 1080p 60Hz. Everything in between seems to be affected by chroma subsampling. Nothing fixes this not changing between 8bit and 10bit, SDR and HDR, RGB etc. etc. Because this problem is so specific to the CX model I believe this is due to LGs firmware."

There have been some g sync related issues but those seem solved
