What are the chances of an app to adjust screen color calibration and/or color temperature?

Just received a 32GB touchpad to accompany the 16GB I already own, and that was going to go to the wife. The 16GB screen is fantastic, but the 32GB screen is green-yellow tint and saturated. Not terrible, mind you, but noticeably inferior to 16GB.

Otherwise though, the 32GB is very well-built. Buttons perfect, etc, where my 16GB with great screen is not well-built. Can't have it all, I guess.

I've opened a repair ticket, and a repair box is coming. But I'd prefer to hold onto this unit if color calibration capability was coming soon.

Any chance?
