Preheat the oven to 175°C.
Spread the bread cubes out on a baking sheet and bake until toasted and golden, tossing halfway through, about 15 minutes. Let cool.
Whisk together 1 cup of the evaporated milk with the 2-percent milk, 1/2 cup sugar, 1 teaspoon vanilla, nutmeg, a pinch of salt and eggs in a large bowl. Add the cooled bread cubes and wild rice. Toss to combine and set aside until the bread soaks up most of the liquid, about 30 minutes.
Stir the blueberries into the mixture and transfer to a lightly oiled 2-quart baking dish. Top with the almonds and bake until the bread pudding is set and golden, 30 to 40 minutes. Remove and let rest for a few minutes.
Meanwhile, add the remaining 2 tablespoons sugar to a small saucepan. Swirl over medium-low heat until the sugar dissolves and turns amber, about 7 minutes. Stir in the remaining 1/4 cup evaporated milk, 1/2 teaspoon vanilla, orange zest, orange juice and a pinch of salt. Bring to a simmer and cook until slightly thickened, about 2 minutes. Drizzle the caramel sauce over bread pudding. Serve warm or at room temperature.
