The final result is I will have to significantly tweak the custom gamma to correct the grayscale uniformity while adjusting color temp to achieve D65.
It is apparent that with a lot of work, the grayscale and gamma can be adjusted to track very well from setting up a custom gamma memory. This requires adjustments way beyond those I have initially done in the RS2, including my own. It is apparent that the custom gamma creates its own LUT.
Sounds like a royal pain Glen.
I've been scratching my head at all of the reviews I've read that stated the RS2 is so close to being accurate that a calibration is almost unnecessary. Maybe I'm picky but my unit although not horrible, was into the 7000 range OTB at the best combination of settings I could come up with. Again, could be far worse and it was very watchable but I don't like that 'Best Buy' look to in image with everything looking a tad on the blue side.
It's good to know that the RS2 can be corrected in home should something like what your customer experienced happen. Lots of time and patience though...
If you ever take a calibration tour anywhere near Michigan or NY State, pop over into Ontario and I'll make use of your expertise.
I'm only a two hour drive from Detroit.
