For now, it is true that most "professional" productivity apps are on laptops / desktops.
Yes, there are ways to take photos and create music on tablets and phones. You can do some basic editing on them, even. But the "professional" tools for photography and music, with all the bells and whistles you can think of, are still dominated by laptop / desktop computer programs. (The dominant programs being Photoshop for images, and DAWs like Logic, Ableton Live, and Pro Tools for music.)
The distinction between "production" and "consumption" devices is indeed kind of too rigid in a sense that, of course, professionals will utilize the creative tools that come on tablets and phones, even if the desktop / laptop programs are the primary tool. Tablets also can shine as an extended interface for desktop programs. (EG: Logic Pro (and others) have apps that turns an iPad into a remote controller for the main DAW. There are programs like Astropad that turn your iPad into a Wacom-like tablet for Photoshop, etc.)
The obstacle is interface. The fine-tuned control of a tablet or (especially) a phone is much poorer than using a mouse and keyboard with a large screen. Until that gets resolved, I doubt desktops / laptops will go anywhere.
