Good question!
No, if you use View menu > View Options, you can choose which information to show in the 2 loupe info views, and then cycle through those views using the keyboard shortcut I.
I have mine set to:
Loupe Info 1:
File Name, Common Photo Settings, Capture Date/Time
Loupe Info 2:
File Name, Camera, Cropped Dimensions.
Most of the time I leave it on Loupe Info 1, but it means I've got most information at my fingertips at all times.
