25 of 802 screenshots have no message in the export within 30 minutes of their EXIF time.
Each screenshot in the set carries an EXIF DateTimeOriginal with an explicit UTC offset, so its time is exact. For every screenshot the three nearest messages in the export within a 30 minute window were computed. These 25 have an empty match array. What that proves is limited and stated exactly: at the moment each was taken, no message in the Claude export on disk was being sent or received within 30 minutes. It does not identify what is on the screen; 23 of the 25 are Chrome screenshots and 2 are Claude app screenshots, by filename suffix.
