What release level of code do you get when you download a disk image (ISO/IMG) of a click-to-run Office 2013 product?

Question

I’ve asked a similar question to this on an Office Community Forum but nobody knows the answer.  So
I was hoping that an IT professional responsible for installing and deploying Office 2013 might know.
If you download an installation disk image (ISO/IMG) of a click-to-run Office 2013 product from office.microsoft.com/myaccount (Account Options:
Install from a disc > I want to burn a disc), what release level of code do you get? 
Now that Service Pack 1 is available, do you get a disk image with Service Pack 1 incorporated? 
Or do you still get the RTM (Release to Manufacturing) level of code?

Answer 1

Diane, thank you for the reply.
I was hoping that someone who has downloaded a disk image since SP1 became available would be able to confirm that for a fact.
I have just found a good description of Click-to-Run on Technet that I didn't know existed.  The link is: http://technet.microsoft.com/en-us/library/jj219427(v=office.15)
The article states:
"Click-to-Run products that you download and install from Microsoft are up-to-date from the start. You won’t have to download and apply any updates or service packs immediately after you install the Office product."
This statement is probably true if you click the Install button on office.microsoft.com/myaccount and install "in real-time" over the Internet.  However, I know for a fact that it is not true if you order a backup disk (Account
Options: Install from a disc > I want to purchase a disc).  All you get is RTM level code (15.0.4420.1017).
So I still feel uneasy about what release level you get if you download a disk image.  I don't want to download what might be the better part of 1GB of code over the Internet only to discover it is back level.
Addendum (6 April 2014): I decided to perform an experiment.  I looked at the size of the data on my backup disk which contains RTM level code.  It is 2.04GB.  I then went to office.microsoft.com/myaccount and clicked to download a disk
image of my Office 2013 product.  The pop-up window that asks me whether I want to Run or Save the file informed me that the size of the file is 2.04GB!!!  I cancelled the download.  I strongly suspect that, if I had continued with the
download, I would have received the same RTM level code I already have dating back to October 2012.  I think this is awful customer service.  To some extent, I can understand the logistical problems of replacing backup disks lying in warehouses
waiting to be shipped.  But I cannot understand why disk images on download servers cannot be refreshed quickly.
