A very interesting article Kosta, thanks for writing it! I've run across it after testing the same, on my own. I can see that you are similarly facing issues with Lambda runtime being 4x slower than local run of the same operation (local time-to-screenshot ~5 seconds, on lambda ~20 seconds). Is this expected? Have you thought about possible Lambda container optimization (ref: https://go.aws/3zRBdGF )?
