Ok, so in production, I dont see the same image artifacts/compression, but there is a slight color/gamma shift. It's totally acceptable, but again, should probably be reflected in the docs.
Specifically, it looks like the image service strips out ColorSync profiles from rotated images. Here are the two samples (before and after) Original image: http://www.pindropper.com/_Media/remote2.jpg Rotated image: http://www.pindropper.com/_Media/remote1.jpg The original image has the following ColorSync profile embedded: sRGB IEC61966-2.1 Thanks for your help!
