Helpful! Can anyone suggest a colorspace that is not device-dependent to use for saving? Ideally one that will be supported for a long time? Our app needs to recover the image it saved, recovering the original pixel values, even as devices change in the future.
The default colorspace for us, working with images sourced from arkit frames, is:
colorspace CIImage: Optional(<CGColorSpace 0x13b1e1c20> (kCGColorSpaceICCBased; kCGColorSpaceModelRGB; QuickTime 'nclc' Video (1,1,6)))
