I'm seeing slight color changes in RGB JPEGs created by the ePUB export when when Image > Preserve appearance from layout is selected.
I compare JPEGs in Photoshop. Before and after files are untagged RGB (created in sRGB space).
Anyone else notice this?
For comparison, I've also used Zevrix's LinkOptimizer to export cropped, resized JPEGs. The files resulting from that have no color change from the original.
Same with using Photoshop's Save for Web: resulting image file has same color as the original.
Looks like InDesign is doing something different in the ePUB export.
