I’ve been using Photo 1.2.1 going through many old family photos, enjoying recovering faces.
I find it interesting that the ‘Realistic’ mode makes more changes in appearance that do NOT faithfully preserve features. There can be a somewhat ‘beautified’ result, which can be a very nice creation. ‘Creative’ does a better job with recovering/restoring eyes, nose, mouth, teeth that most closely resemble the original actual person.
