Lightroom Mobile RAW rendering issue – artifacts in transition area between colors

[m6p5c]

I discovered out that LR Mobile on my iPad does not properly render the gradient transition between different colors in RAW images. 

Attached are three screenshots of identical raw file in Loupe module from LR Mobile(iPad), LR desktop(Mac) and LR Classic(Mac). 

 

   

As you can clearly see, there's a sort of halo around the green spots among the blue water. And I observed very similar issues with other RAW files. 

  

It seems in most cases this haloing mostly occurs around a transition between green/yellow regions and a blue region, in the blurred background. 

I could not reproduce such issues with JPEG image files.

This issue carries onto the files Lightroom Mobile exports: It's visible in TIFFs tossed to Photoshop Mobile or JPGs. 

Also this issue has been around for quite some time, I remember noticing a very similar phenomenon last winter. 

Some tech specs: 

Used device : iPad Air 4th gen(iOS 14.7.1)

Used software: Lightroom Mobile for iPad(v 6.4.0 43023A/60)

Used camera : Sony a7iii (.ARW file)

If Lightroom on your iPad is loading these images from cloud storage, you are probably working with "smart preview" copies of your images.  

If you select one of the images that doesn't look right, open it in the Edit mode, and then tap on the cloud icon and choose "Get this original" ...does this help to view/edit the original image?
