Can lambda know the specific attribute which changed in the dynamo db table update, when a lambda is triggered by dynamo db table update item??

My client has an architecture to trigger a lambda whenever the dynamo db table is updated. However, my client needs to perform a check on the specific attribute which changed. The lambda payload gives the new and old image. However the lambda should compare and check what changed between the old and new image in order to proceed to the next step. In this case, is there any way the lambda can know which specific attribute changed when an item is updated in a dynamo db ?
