P: RGB Channels for Lr Mobile

Now if I'm correct, this would be incredibly difficult to optimize for lower powered devices such as a smartphone. Most people don't understand just how deep into color data that this tool goes. The other color adjustments manipulate entire pixels, (the r,g, and b) at once in accordance to the desired result. The RGB Calibration tool splits pixels and only adjusts ⅓ of the pixel (the r,g, or b) individually. Talk about minute detail, I'd say it doesn't get any more miniscule than dividing a pixel! Maybe my assumptions are wrong, but it seems like that's how it would work based upon what it does and how it is labeled. Now that I've shared my unsolicited ever powerful knowledge, lol, my request is that you find a way to optimize RGB Color Channels Calibration for Lightroom Mobile for smartphone, or in my case, premium chromebook.

Have you checked the Curves tool (under Light)? It has an option for individual color channels. The 'Mix' tool (under Color) also offers powerful options to manipulate individual colors.

Not even 15 minutes after making this post, I am questioning my figures. Perhaps the other color adjustments dig just as deep and maybe work harder. They have to divide pixels as well in order to lighten or darken a combination of red, green, and/or blue to create the desired color. They may not have to work across every single pixel (as does the rgb channels tool), just the ones used to create the color in the range that is being adjusted. However, the pixels are still being divided and each channel is being adjusted, but simultaneously to create a specific color within that range. That being said, the unique method that the color channel tool uses creates a serious weapon in color adjustment, thus why I'm requesting it.
