Undertale and Deltarune definitely aren't sincere in the aesthetic sense of the word. I think that it's more accurate to say that they sincerely pander to a specific cultural niche: Tumblr, SA, Homestuck, Tails Gets Trolled, etc., Internet culture and communities so saturated with self-aware absurdity that it's "hip" to treat them with sincerity. Toby's "sincerity" comes from an inherently ironic, self-aware juxtaposition, and I don't think that's true sincerity. It's one big in-joke.
tl;dr I agree, thanks for your autistic rant OP
