His painted version shows great care for painted Alicia, especially considering that Aline, who created him based on her own feelings and memories, is known to mistreat Alicia and even painted her as a mute burn victim while being fully capable of recreating her daughter before the tragedy.
Also, compare his real version's attitude to Alicia and Verso. Alicia in Act 3 is technically Maelle with Alicia's memories, but despite that, Renoir clearly cares for her. Verso's situation is the same, but he isn't Renoir's now-dead Verso, so Renoir never calls him "son" and appears very distant when interacting with him in cutscenes.
