The only information I’ve seen says that some games are graded for 1000nits and others to 4000 or 10,000 and the latter are the ones with issues. However, I cannot find which games are which.
Games are usually not even graded.
Therein lays the majority of the problem.
Most games will take whatever you throw at them in terms of brightness. Add an hdr mode on top of that and it can play havoc with some brands choice of tone mapping.
Some newer releases are wising up to the need for internal hdr calibration settings (paper white and peak white) to help over come the side effects and limitations of tone mappers on television sets, however since there is no set standard for this in gaming it isn’t widely supported.
What ends up happening on the lgs is he over all specular detail highlighting will be muted down in favor of trying to rectify detail that may exist within it and the picture will lose much of its hdr “pop” as a result. It’s a compromise that nobody really asked for that has detrimental affects on presentation depending on the game and how they have chosen to implement their hdr support.
That’s not to say you cannot enjoy or like how it looks, it’s saying that the hdr game mode does “suffer” from reduced brightness in peak areas because of how the tv interprets the incoming hdr signal while in game mode.
dynaimic contrast somewhat helps return the look of the peak highlights, but since it’s already being compromised as an incoming hdr signal by the tone mapper it’s not really rectifying anything. It’s simply giving the preception of increased brightness by allowing the tv to ignore near white detail.
It’s a bandaid that offers its own set of compromise on top of an already compromised presentation.
