Only Adobe would have the ability to integrate Color.io into Lightroom Mobile and unfortunately they haven't made an offer to me yet :-D

Create XMP Profiles for Lightroom with Color.io

You should think of Color.io as a tool that allows you to create advanced Lightroom Profiles, not as a tool that replaces Lightroom. You can export XMP profiles for Lightroom directly from within Color.io: https://www.color.io/user-guide/create-luts-for-adobe-lightroom

Don't use JPEG for intermediate rendering

• Use Tiff or PNG for lossless renders.
• Use wide gamut Display P3 color
