My bad for attempting it...
If in doubt, you can always revert the TV to factory settings.
But, it shouldn't be that hard to set all the luminance values back to zero. You just go to IRE 5, set it to zero. Then you go to IRE 10, set it to zero. And so on. The only one that has an additional setting is IRE 100, where you set the overall luminance target of the entire curve.
Someone in previous posts mentioned it is as easy as making a few tweaks to the IRE. This affected my luminance and I am not sure where that setting should end up so can someone list the steps to take to make these tweaks and what the end result should be.
You just raise the luminance a few notches and then observe the test pattern to see if shadow details emerge. Nobody can tell you what your TV should be set to. . . you have to observe for yourself.
Also, please keep in mind, if you don't have a meter and you're just an average Joe/Jane, there is no "correct" setting so long as you think the TV looks good. If you already think the TV looks good, stop messing with it!
Also am I correct in that this adjustment only affects the particular picture mode I am in when making the changes.
Yes. And only that mode for that input. If you change inputs (from HDMI 1 to HDMI 2), you'll find those modes remain unchanged.
If all else fails how do I get the settings back to the way they were right after the update before I tweaked them.
See above, Just go through each IRE step in the 20-point adjustment range (5 IRE up to 100 IRE) and set to zero. If you messed with the 2-point adjustments, I have no idea. . . haven't been in there myself.
For full peace of mind, there's also the factory reset option. But then you've gotta get everything set back up from scratch. It's not that hard though. . . sometimes a fresh start feels good.
