There have been purported 'camera comparisons' for the 7/7 Pro vs other phones now for weeks, but it's far, far more likely than not that they aren't actually using using the 7/7 Pro (especially if they don't even show the physical phone (not just a stock or reused image) in the video). It's a really easy thing to fish for views by saying "Shot on a Pixel 7 Pro!"
If someone were to actually break the embargo on hands-on performance/function reviews (which runs till late next week), even then it would be on a device that is likely not using the final software that will be considered the "release" version.
