First of all, cheers for sharing your knowledge on the subject.
Let me highlight the fact that I am only concerned about the video recording capabilities of the two sensors. I initially tried to draw some conclusions earlier
on this thread.
You say it rather has to do with the implemented auto exposure meter method (which understandably suffers in mobile phones vs DSLR). Unfornately, in order to be able to make a direct comparison off the two sensors, we need identical samples to draw conclusions from. And the only ones I managed to find is this (good
light) and this
(low light). Under low light, the IMX240 retains more detail - no question. Under good light, ISOCELL seems to retain more detail in most areas. Like in the grass (or the leaves of the previous sample as you mentioned). And it somehow manages to brighten up areas better compared to the ExmorRS. But again, some areas (like the plastic people) seem more blurry in the ISOCELL sample.
If I am not mistaken, under video recording, you don't have many options to fidle with e.g. lower shutter speed. Most things are set automatically. So, in our previous sample with the trees when the phone is facing up, both sensors would behave more less the same., right? I am not interested in capturing the sky - I am actually interested only in brightening up the foreground (leaves). Apart from HDR, is there any other option I could use to get better results. Would any of the two sensors have any advantage here (no matter how small...)

Your concept is right in some parts. In such case, lower the shutter speed should also improved the result(but sky may get over exposed while foreground could show out now) but usually night mode will also take photo at high shutter speed at day light(when it detects many light there and think you wrong picked the scene mode), night mode only will take photo with slow shutter in dark environment only. You need a manual shutter speed supported camera phone.
