I must admit that I don't know if changing values in the settings would lower or aggravate the input lag.. But I guess rtings would have write something if some options were to dramatically change the input lag value, so I wouldn't worry too much about that.
About HDR, on the same review we can see that, in Game Mode, 4K HDR and regular 4K gaming have the same input lag values : 21.3 and 21.4ms respectively. So it doesn't seem too far-fetched to assume that HDR wouldn't change the input lag value one bit in picture modes other than Game Mode.
About the thresholds for tolerable input lag values, I'd say 63.0ms is a bit too much for me, as a long time PC player I'm pretty sure I would feel the delay. The 46.4ms delay in 1080p gaming is a bit more tolerable but it's still too much, IMO, for critical gameplay such as : any competitive multiplayer mode, fighting games, racing games, platformers, fast FPS's like DOOM etc.
