Was this issue fixed. We have an image that we are not able to scan through the camera because of the lighting (or negative colors)

image from ios 1

When we change the lighting on the image then it works fine. Also, this image scans fine on react-native-camera

hmm, is there anything that react-native-camera does especially to recognize these images?
