Image::cleanImageByPath converting large CMYK Tiff to RGB, ignoring general settings

Description

I've been struggling with this issue today. When I upload a large CMYK TIFF image to a standard volume (example file here) , the final image is converted to RGB color space, and the colors are off. (Attaching thumbnails of before and after). I've set my config values as such:

    'preserveImageColorProfiles' => true,
    'preserveCmykColorspace' => true,
    'optimizeImageFilesize' => false,
    'preserveExifData' => true,
    'maxCachedCloudImageSize' => 0,
    'rotateImagesOnUploadByExifData' => false

but the issue persists. Only if I comment out the Image::cleanImageByPath call in craft\elements\Asset->afterSave does the image save as expected. I did some code diving to see if I could pinpoint whether there was a transformation or something that was obviously triggering it, but couldn't turn up anything. Not sure if this is an issue with ImageMagick or not.

Steps to reproduce

1. Download linked file above
2. Set config as above
3. Upload image file to craft volume
4. View the file to see the obvious color difference, or download it to local machine and inspect colorspace, see RGB
