When Photos first loads an image, it scans the picture to see if there's anything in there that it thinks might be a face. If it finds what it thinks is a face, it puts a little circle icon in the Info preview to let you know. Then, if it's unidentified, it lets you offer a person's name to go with the face.
If Photos doesn't find the sort of details to make it think that there is a face there, then the face icon doesn't show up, and you have no "face" to identify. The picture is never scanned again and, even if it were, Photos wouldn't see anything it didn't see the first time. So you cannot add this picture to a Person album.
On a Mac, by the way, you can manually add a face and identity. I do this with pictures of people who are turned away, for instance. That picture will be put in the right Person album, though it is not used to add their features to Photos identification. The picture, synchronized with iCloud Photos, will appear in the iPhone's Person album. But this isn't available in iOS or iPadOS.
Another thing that many of us do is include the name in the Caption field in the Info window. Then, if you search for, say "Caitlin Clark," you'll get the ones that Photos recognized and also the pictures with "Caitlin Clark" in the caption.
This is good practice in any case. Face tags can be lost in OS update, and they don't transfer with an exported image file. But captions export with the picture. I include the name in the caption for every picture that has a recognized face, as well as for un-recognized faces.
Hope that works for you...
