From a trusted insider at AVS Forum:
GAME MODE HDR:
Distribution of the firmware update has already begun (I have it on my Q9 but cannot test it because I no longer have a game console). This update will trigger HDR settings (color space, brightness, contrast, etc.) while in GAME MODE.
SCREEN BRIGHTNESS FLUCTUATION:
This effect is random and appears to affect different signal sources to varying degrees dependent on content. No timeline on a potential fix.
AUDIO SYNC ISSUES:
Unsolved at this point; the lab setups do not consistently reproduce the issue, making it virtually impossible to identify the cause of glitch.
HDR "POP-UP" NOTICE:
The software engineers are looking at the possibility of reinstating this feature. No timeline given.
ENHANCED INFO BANNER:
They are looking into whether the current processors can enable the TVs to display (for streaming sources) the level of detail the INFO BANNERS on the 2017 UHD BDPs provide for discs.
CALIBRATION-RELATED ISSUES:
The head of USA tech support wants to review the severity and number of incidents prior to committing resources to address any problems. Please go to the Samsung tech support chat, and discuss your specific issues with the CSRs; send me the ticket number via PM so that I can forward them to the head of tech support.
HDMI 2.1 FEATURES:
2016 & 2017 TVs are being tested to see if a firmware revision will allow full compatibility with HDR10+ via HDMI. VRR is specified primarily for the gaming environment, and will more than likely not be featured until the debut of the 2018 models, as is 4K @ 120Hz.
