I had to add this, it is too funny.
So, I upgraded for several reasons, but to me, the biggest was to be future proofed for gaming with hdmi 2.1 and 4k/120 when it comes next year, but a big part of that was so I could then lay rdr2 on the series X and hopefully see it beyond the 30 fps it is locked at now.
Anyway I have been playing since launch on a pre hdr tv, so I have never played rdr2 with hdr on.
I figured that too will be an added benefit, well turns out the HDR in RDR2 doesnt work properly it isnt really hdr.
High dynamic range means the range between black and the brightest bright is greater than normally, so you get brighter highlights and specular highlights you can see etc..
But in RDR2, the range stays exactly the same it just moves from darker to more bright, but the gap in between never fluctuates, so it isnt HDr, it is some form of a fake HDR.
Anyway with xbx1x and rdr2 if you use hdr on an LG oled anyway you get this bluryness while you are panning around, it is distracting and terrible looking, the only way to clear it up is to disable HDMI deep color, which then disables hdr 10.
So, irony being what it is, the tv I bought to play RDR2 in all its glory wont let me play it in hdr!! lol thats funny
IT works great in all my other games, they look so amazing, I have never seen them like this before, so playing them all again is a definite to do now, but I thought it was funny, that the one game I really wanted to see this enhancement on I can not.
Here is a better explanation of the hdr in RDR2
