Different result on Android that on Editor/iOS

Good day everyone. Can't solve some problem with color replacement in shader. Here's original texture



I trying to replace all green to some different color
Result on PC/Mac/IOS:


Result on Android device:


It's simple vertex and a bit complex fragment shader on Cg. Sorry i can't share it's code. Color comparison happen in HSV color space via "hsv distance" (almost like normal distance vector3)
