Is there a difference between the "images+stream starter plan" and paying for each service separately?

hello
I have been using “images” for a long time. I need the stream service and would like to subscribe to it. I am not eligible for the images+stream starter plan.
I need to subscribe to STREAM’s $5 plan in this case,
Is there a difference between subscribing to the two services separately and the starter plan (images+stream)?
