With regards to videos, exiftool has no ability to remove data that is embedded in the stream, such as GPS tracks. As with the APP14 segment, no identifiable data is held here and there's no real reason to remove it. Most modern software will read ICC_Profiles, so you will usually want to keep the data as wywh shows. Image colors may be affected warning when this happens. Exiftool will issue a ICC_Profile deleted. When there is an ICC_Profile in the image, using -All= will change the colors/look of an image if the the viewing program is aware and can use the profile. The APP14 segment contains no identifiable data, so there is never a reason to remove it. There's only a couple things I would add. Wywh's list pretty much covers everything.
