How to highlight available services from unavailable ones?

I merely retrieve a list of company services from database that I just have to display on a web screen.

Basically, result is composed of available services for the user and unavailable ones.

What is a good way according UX experts to display results so that it's pretty easy to make the distinction between available from unavailable ones?

Currently, the existing display on the project I have to work in is the following one:

enter image description here

Blue check means available and grey check means unavailable.

One of possible issues with this strategy is that if there are no available services, user would have the illusion that everything is checked even if checkbox's background appear in grey.

(Used language in this screen is French)
