Great questions! Answers below . . . and thanks for trying my settings. I hope you will enjoy them as much as I do.
1. Yes. Each format causes the TV to load a separate color tuner table for that format. Eg. - SDR has its own table, DV has its own table, HDR-10 ditto. The only way to access the table for DV or HDR-10 is to play DV or HDR-10 content; and while it’s playing input the color tuner settings.
2. No. The color tuner / 11point settings are global regardless of input. Only, the picture mode needs to be set for each input. This is a one time thing.
Suggestion: What I would do is modify the "Calibrated" picture mode with all the settings for SDR including the color tuner using HDMI1. Next, save that picture mode with a custom name. Now, when you switch to the Smartcast input, all you need to do is choose that custom picture mode once, and it will stay that way until you decide to change it.
3. It will be. The color tuner / 11 point settings are global regardless of input. Since each HDR mode get’s its own CMS table, those settings will also be global while playing the respective HDR formats.
4. Currently, I change the backlight from 40 to 50 for DV and HDR-10. For HDR-10, I also reduce the color setting to 45. ( This will probably change once I get the HDR training from Calman next week. I’ll post the settings once they’re ready. ) The TV will remember the changes you made, so it’s a one time thing just like most of the things above.
NOTES: Color Temp is the one other setting that get’s it own color tuner table. Don’t change it. ( You don’t want to anyway ). After my HDR training next week, I should also have some nice DV settings to go along with the HDR-10 settings.
