See https://docs.rs/arrow-array/latest/arrow_array/array/trait.Array.html#method.is_null In particular > Note: For performance reasons, this method returns nullability solely as determined by the null buffer. This difference can lead to surprising results, for example, NullArray::is_null always returns false as the array lacks a null buffer. Similarly DictionaryArray, RunArray and UnionArray may encode nullability in their children. See Self::logical_nulls for more information.
