Can one upload a Photo including it's title to iCloud

If you assign a title to a photo in the Photos for Mac application, and sync your Photos Library with iCloud Photo Library, the titles will be shown in the Photos.app at www.icloud.com.

Actually, iCloud Photo Library will be storing many metadata of a photo, the title, the filename, the description, the keywords, and these metadata will sync to any Mac that is syncing with iCloud Photo Library. The Photos.app at www.icloud.com will only show the titles, however, not the filenames, descriptionss, and keywords.
