Add "Keep color profile when possible" just below "Clear existing metadata" as an Exiftool setting.

32. "How do I safely delete all metadata from a file?"
First of all, all metadata shouldn't be removed from some file types (such as RAW images) because this information is necessary for display of the image. JPEG is the most popular image format and most suited to erasing all metadata because the image and metadata are well separated in this format. However, even with JPEG images care should be taken because the metadata may contain color space information which should be maintained to preserve the color rendition.
Here is a command that may be used to safely delete all metadata from .JPG images in a directory:
exiftool -ext jpg -all= --icc_profile:all -tagsfromfile @ -colorspacetags DIR
This command deletes all metadata except the ICC Profile if it exists, then copies back any EXIF color space tags (adding any mandatory EXIF tags using default values if necessary).

This would fix [Warning] [Exiftool] Warning: ICC_Profile deleted. Image colors may be affected.
