Update: In movie mode in a dark room, I am no longer noticing any issues! Any minor backlight artifacts are so subtle that I can’t notice in any ordinary viewing condition, and for those that do occur, I’m pretty sure they are due to the particular content interacting with the FALD algorithm (not a defect in the TV backlights) — because I haven’t noticed any issues in any other content so far.
Thanks again for letting me know about the bug (or whatever it is) in standard mode with high local dimming. With movie mode and high local dimming, or standard mode with medium/low dimming modes, I am now very happy with this TV, and am really enjoying it so far!
Regarding color temperature: Interestingly, Warm2 seems much too warm to me at least perceptively — most content renders skin too red and skies not blue, etc. Warm1 seems perfect though. I suppose there’s no way to know for sure without a calibration disc, though.
Standard color temperature definitely seems too blue. I wonder why Samsung would name it so incorrectly then? Seems like they’ve been doing this for a while, too.
It is also weird how the different video modes (e.g. Dynamic, Standard, Natural, Movie) are not just presets but appear to have some hidden internal settings. Because even if I set all the settings between e.g. Dynamic and Standard to be the same, they look completely different. I wish there was documentation on this that was more precise about what exactly these do.
