Importing RAW photos to Lightroom IOS destroys the quality

Hello,

Recently I've started shooting RAW photos with my iPhone 13 Pro. Today I went into Lightroom Mobile for IOS to edit one of my new photos, and I noticed a serious quality distortion when importing the RAW photo (which has DNG on it in Lightroom's preview). Regular non-raw photos are perfectly fine. Any ideas what's going on?

here is an example; left picture is exported from Lightroom (no edits, just imported then exported), and right is the original.
