I wonder if when something is not documented but experimentally confirmed we should not record it with a comment.

The configured vblank_min setting of 151 (meaning VTS of 720 + 151 = 871) is far higher than the setting that works on the sensor, and there are no obvious restrictions stated in the datasheet. Reduce the vblank_min to allow for faster frame rates.
