At least the input lag is a bit lower due to the OLED screen if nothing else.

FYI, many games can look worse when using HDR due to poor in-game implementations. Having had access to HDR since the Xbox One X days there have been many times I’ve turned it off after finding the picture quality subjectively worse. This also is even more of an issue when using PC titles and the lack of HGIG mapping that the consoles have.
