Alright, I think I'm finally done. I've tried for quite a while, but it's not going to get any better than what I've done now from my experience.

The grayscale was already as good as it can get, so that was pretty much unchanged. The same goes for the contrast ratio.

I was able to get better color accuracy in the end. Previously I had good dE values for the colors, but the x/y values were further off than what I wanted. I found that by raising the general color setting even more and then compensating by lowering the intensity of each color in the color space menu, I was able to get better accuracy in the x/y values. Which in turn gave me even better dE values. Green though is still a color that's simply under saturated, there's nothing you can do about it. None the less, it's still pretty close to being where it needs to be. And if you look at the file, you can see that every other color if pretty much perfect.

I'm very happy with everything now. So I think this was my last calibration for a while. Special thanks to ra004e for letting me borrow his eye-one sensor so I can do the calibrations and post the results, it's very much appreciated.

For those who want the white balance settings for the user menu. They really haven't changed much at all from my previous Warm-1 settings. So you'll be fine using the previous White Balance settings I posted combined with the rest of these settings I have now. I'll post them together below so you won't have to keep searching for them.

Pretty darn good picture quality. With Zerog6's settings it was just "a tad" red, but better than most until I tweaked it some more and borrowed some of Sirluckyj's settings. Thanks Sirluckyj!!

I've also attached a text file of the service menu walkthrough Zerog6 created from a message interchange with KJGarrison. I must warn you to be careful when going into the service menu. I take no responsibility in any screw ups that may happen. It's also prudent to jot down the original settings before making changes, so that you can revert back when needed.

I tend to watch most things in Dynamic mode (just like the vivid colors better) sometimes in standard. If I try these calibration settings do you thing it will fix my problems? Is it possible the firmware screwed someting up?

Have you got your problem fixed with your 750 (1012.2)
After I upgraded mine my picture quality just sux. Lots of artifacts, grainy, colors don't seamlessly radiate they fade in steps. Some shows I have vertical lines going through the blacks.
I have gone into the Expert settings and adjusted those settings which help in movie mode, but in standard and dynamic it hasn't helped at all.Please let me know if you have or not got your issues fixed. I am contimplating calling Samsing and going that route.

I'm praying this works because it's my only real complaint. Sometimes I wonder "what if?" about moving to a 52B750... sigh.
