MTIColorLookupFilter of MetalPetal output incorrect result


I test the MTIColorLookupFilter of MetalPetal framework with the default lookup image lookup.png on Iphone 6 iOS 9.3.1 but the result image was strange as below image. When I tried to test on Iphone 6 iOS 12.0 the result was correct as I expected. Please help me to fix it!
