I have a few images with Getty. It hasn't made me rich but I have made a few bucks, far more than if the same number of images had been placed with a lower-end site. I don't expect that to change with the new arrangement - if anything, it might get better since the images may receive targeted exposure. For example, a travel-related blog embeds one of my images - a travel company reads that blog, sees the image and thinks "nice! we'll use that in our next brochure" and, bingo, I get another sale. Contrary to the online situation, print media generally don't steal images. So overall I'm happy that Getty has gone this way.
The embedded image is very crudely downsized - utterly unusable for print and distinctly poor quality even for a blog. This image, for example, is bitingly sharp in full-res but almost worthless in its embedded version:
