Drain the crab and pick out any shell bits. Pat dry with paper towels.
Beat the softened cream cheese, mayonnaise, and sour cream in a bowl until smooth.
Stir in lemon juice, Dijon, Worcestershire, Old Bay, garlic powder, paprika, hot sauce, salt, and pepper.
Fold in the crab, green onions, and dill gently to keep the lumps intact.
Cover and chill until slightly thickened and flavorful, about 15 minutes.
Spoon onto cucumber rounds, crackers, or toast. Garnish with extra dill or Old Bay and serve.
