I have a C8, but that is my guess as to what most of the B7/C7 owners have been asking for.
Even if HDR technicolor is what is most accurate, HDR Cinema (or is it HDR Cinema Home?) is the level of brightness people want in HDR game mode, which the update did not address.
The C8 HDR game mode with dynamic tone mapping is much brighter than HDR game mode on the B7/C7 and there is no reason that should be the case, other than LG wanting it this way.
I think some people just want "HDR Standard-like" luminance back for HDR Game as it was before both 2016 and 2017 got patched with the "Cinema" (not Home) tone mapping.
What these people is not realizing is that eye-melting luminance in a dark room and the "more pop" they refer to for neon-like colors is not the best default to have for gaming to begin with, but I can perfectly understand how in order to get close to proper luminance when gaming people tried the PC HDR Standard route when HDR Game (even with DC) still wasn't matching HDR Technicolor either (I also personally recommended it as an Option when PC Input got fixed with 5.80.04)
Now getting so close to HDR Technicolor with Active HDR results when using HDR Game Dynamic Contrast is a giant improvement over the old HDR Game and older "HDR Standard", and if still these people complain for not having back the latter, they should probably re-think their idea of Picture Quality or should at least reconsider the priority of their wants compared to objectively more balanced solution for all the others.
LG will never bring back HDR Standard profile for HDR Game for a reason.
Regarding 2018 Series' Dynamic Tonemapping (basically the same as Active HDR) for HDR Game, LG is probably right also there, as real Active HDR require more processing power to process every frame and drastically increases lag in 2017 models when using it outside HDR Game mode.
2018 faster chipsets can simply handle it without added lag.
