Is it okay to highlight how a website looked before I worked on it?

I’ve got one question for you, web designer pro: is it a dick move for a freelance web designer to point out how a site looked before they started working on it?

Here’s the context of the question. I’m a partner in a small design shop. We’re just getting our business off the rails (we’ve got clients and no live website for our business!), and we’d like to write case studies about our clients on the website to be. In one instance we’d like to show before and after screenshots of the site they hired us to redesign, along with text describing what we did.

The idea for having before and after screenshots of our clients’ websites came from plastic surgeon’s websites. They show before and after photos of their clients, so why can’t I?

I’d appreciate your feedback on this question. I have no sense whether it’s a dick move or not.
