What would be the latency of the images?

Depends the way you look at it. The final data is generally available within a couple minutes, but the data itself is not collected instantaneously. At least for the full-disk scenes, the collection takes 11 minutes so the top of the image is captured 11 minutes before the bottom.
That said, the raw data is available through an S3-compatible service, here: https://osdc.rcc.uchicago.edu/noaa-goes16
With documentation about how to navigate and use the files here: http://edc.occ-data.org/goes16/getdata/
So it would be possible to script together something that cooks out a nice high-rez full disc image every 15 minutes.
For fun, here's one of the full disc frames we cropped in from:

Note that even though its 2712x2712 pixels, that's still way smaller than GOES16's potential resolution. The highest rez versions of this image that I've encountered go over 10,000 by 10,000...
