Slice cucumbers into ½-inch thick rounds. If they're really watery, pat them dry with a paper towel.
In a medium bowl, mix together cream cheese, chopped dill, lemon juice, salt, and pepper until smooth and well combined.
Spread or pipe about 1 teaspoon of the cream cheese mixture onto each cucumber round.
Top each round with a small piece of smoked salmon, folding it to create a little ruffle effect.
Garnish with a tiny sprig of fresh dill and a caper if using. Serve immediately or refrigerate for up to 2 hours before serving.
