I've loaded some Adobe RGB colourspace JPEG photos on to my iPad Pro 9.7" using a special app instead of iTunes so that the colourspace is not changed. The iPad Pro 9.7" has the broadest colour range of any Apple mobile device. If I open one of these photos in LR Mobile and use split screen to see the same photo side-by-side with say, the Photo app, there is a noticeable difference - as I would expect. LR is showing the Adobe RGB version and Photo is showing it in sRGB (because iTunes converted it when sync'ing).
Here's the problem. If I then start to edit the photo in LR Mobile - say by adjusting the exposure - as soon as I begin, the colours change markedly to match the version I see in the Photo app. If I reset the image it makes no difference. It appears that the colourspace has been permanently changed. I have to manually delete the image from LR Mobile and reload it to get back to the Adobe RGB version.
This means that there is no point in using LR Mobile to adjust my JPEGs.
I have tried this with iOS 9.3.1 and 9.3.2. 'True Tone' was off.
