Acrobat Pro DC does have a Snapshot tool. You can call it into action by clicking Edit> Take a Snapshot. If it's a tool you will use with any frequency, you can add it to your toolbar by right-clicking on a blank are of your toolbar, and selecting Show Edit Tools, and selecting the Take Snapshot option. This will add it to your toolbar and therefor make is easy to call into action. It's not the Right-click action you are asking for, but it is a way to quickly do a snapshot.
I hope this is helpful.
