Confusingly, every manufacturer calls the SAME THING something different.
LG calls it "HDMI ULTRA HD Deep Colour".
Please read the "HDMI modes" link in my sig for the comparison of modes possible.
Just turn it on. NB: If you get picture problems, it could be that you are not using a suitable HDMI cable. You need a "High Speed" cable which can carry the extra bandwidth signals required. Some HDR modes need the full 18Gbps. It is not enough to use a cable which claims to transfer the full 18Gbps because there are many dishonest manufacturers and retailers who use deliberately misleading statements.
For this reason always look for the Premium Certified label
Premium Certified cables are NOT expensive - but many crappy cables which are not certified, are expensive!
This is the ONLY thing you ever need to look for on a HDMI cable - it's really simple and please don't be sucked into thinking you need to read a big long list of specs.
If it's got that badge, you're good. If it doesn't, you don't know and it's the Wild West.
So now I am quite confused.
Is HDMI Deep Color setting on an HDMI port required to experience HDR?
Don't know why you are confused.
Just turn it on.
Is there any way to determine if an LG TV is receiving/displaying HDR metadata from a given source?
Yes, very easy. The TV bends over backwards to tell you!
If the source is HDR10 or HLG or Dolby Vision:
- The TV will show a "HDR" or "HLG" or "Dolby Vision" piece of "toast" (pop-up) in the top-right corner of the screen when it switches.
- The info panel will say "HDR" (waggle remote, click on top left, click again)
- The list of Picture Modes will say "HDR" (for HDR10 and HLG") or "Dolby Vision" at the top.
