So much has changed with the Samsung Galaxy Z Fold 7 that you may not have noticed one of the most crucial differences between it and the Galaxy Z Fold 6.
After four generations of under-display cameras on the Z Fold's main screen, Samsung has finally called it quits and moved back to a punch-hole camera. It's also over twice as detailed, using a 10MP sensor rather than a 4MP one (that is technically 16MP - it's complicated). Arguably, the punch-hole is less optimal for the big inner display that defines the Z Fold, but it should be much better for taking actual photos.
