rose_luminance_2 is the same as rose_luminance. Both are colorspace gray, type grayscale and gamma=1 and the min,max,mean,std are all the same.
rose_luminance_1 is different. It has apparently undergone some change by the -colorspace RGB, which I did not expect, since it still results in gamma=1. The IM developers would have to explain.
