Presets saved under Adaptive Color profile include hidden Camera Calibration settings

[ZCUDD7]

I’ve recently started using the Adaptive Color profile as the default base for most of my images. While building a modular preset toolkit (e.g. curve-only, sharpening-only presets), I noticed consistent color shifts when applying these presets to new images, even though Profile, Color, and Calibration were not selected when saving them. After moving to desktop and inspecting the preset XMP files, I found that presets authored on images where Adaptive Color was already applied contained non-zero Camera Calibration values (e.g., BlueHue, BlueSaturation, etc.), whereas identical presets authored from a neutral-origin image did not. These calibration values are not visible or editable in Lightroom Mobile/iPad, but they persist and affect color when the preset is applied elsewhere. I’m trying to understand whether this behavior is expected or an unintended side effect of authoring presets under Adaptive Color.

Below is an example from the .xmp file for a preset that I authored which only selected Detail/Sharpening as the settings to save; it was built from a photo that had the Adaptive Color preset used. Notice how there are non-zero settings included for Camera Calibration (e.g. Blue Hue and Blue Saturation). 

crs:Version="18.1"
   crs:ProcessVersion="15.4"
   crs:Sharpness="150"
   crs:SharpenRadius="+1.0"
   crs:SharpenDetail="25"
   crs:SharpenEdgeMasking="80"
   crs:ShadowTint="-5"
   crs:RedHue="+15"
   crs:RedSaturation="+15"
   crs:GreenHue="+50"
   crs:GreenSaturation="+15"
   crs:BlueHue="-15"
   crs:BlueSaturation="+20"

Version of the App: Latest as of 1/1/26 (Cloud app)

Platform and OS version: MacOS Sequioa 15.6 and iPadOS 26 (reproduced the issue on both platforms)

I assume this is as designed. Camera calibration cannot be edited on an iPad, but any settings are still applied. That means that when a preset is created on an iPad, from an image that has non-zero values for camera calibration, those settings will be included in the preset in order to make the preset work as expected on that iPad. It is an arbitrary decision, of course. Bottom line: do not create presets on an iPad from images with 'hidden settings' like this.

Note: it would be strange (and indeed perhaps a bug) if this only happens when the adaptive profile is included in the preset, but there may be some special interaction between this profile and non-zero camera calibration settings that makes this necessary. Does it not happen when the preset includes another profile?
