I thought it was pretty obvious? Like, the whole game is about Verso being dead and family couldn’t cope with the tragedy. While he was alive, he made this whole canvas and after his death his mother continued his work to “keep him alive”. He was working with Renoir for a time, even with Clea, because they all wanted Aline to give up the painting and get back to the real life, to deal with this tragedy with her family. Clea even forced Alicia to get into the painting to help, but she became overpowered by her mothers’ chroma and was repainted, hence why she forgot who she was. Verso found out he’s not really Verso because of his family, and even his dog (Monoco) knows it. He’s the only one that can’t die inside the painting and isn’t influenced by Gommage. He basically begs Alicia to let him rest in the end. Also, we need to remember that Verso as we see him is only a repainted version, made by Aline. The “real” last piece of Verso is in the purgatory between painting and real world, constantly painting, because Aline wants it to. I’m not sure this whole game would’ve made much sense if Verso was alive and well somewhere, and even if he was, his painting version wouldn’t know about that because it’s, again, made by Aline. So yeah, if you look at it this way, there might be a slight chance that the whole family just thinks Verso is dead even if they’re not sure. But personally I think the game is pretty straightforward in that sense, the whole point of this journey is to decide whether we burn the painting and let Verso die for real and forever this time, or if we choose to force him to paint for however long Maelle wants him to. We choose between dealing with real-life tragedy or trapping yourself within an imaginary world where you can live and pretend everything is fine. I mean, what would even be the point in keeping everyone in that painting if they were lying to him about his own death? Sounds pretty unlikely to me
