Great way of presentation.

Their chips really are one of the best low end, and have their own arms, and dead cheap and low energy, upto rather powerful. The chip in the Yi 4k+ is not their best, but encodes 4kp60 video at around 120mb/s, but can do much more, and I think it has 10 bit HDR mode (but hdr is best 12 bit plus. Consumer HDR goes to 12 bit, but for professional post reductions in results you usually want two more bits, and high end cameras are using two more again). The reason for more bits practically is to save the image rather than having problems baked in (as well as selecting better image levels in post and processing, whichnI don’t think people here would be bothered with). Basically if part of a scene gets to bright or burner out, or things you want to see in shadows go black, you have the extra 2+ bits (consumer HDR is baked into consumer playback media at 10bit possible) to push it to a more desirable level, or other post processing truck to rescue it.

It should have 8k sensors inputs. The older version had 6 sensor input for drone based Artificial intelligence, as it had, and the new one should be, the most powerful ARM could with a very powerful GP gpu. Now, an audrino system based on that chip (and it could probably easily emulate audrino binaries full speed.

But, without good pictures from ultra hd or 4k, audrino camera is a curiosity, unless you want to make a quality fullhd/2k pro video camera out of it. 4kp50/60 hdr wide color gamut at 10-14 bits, are also good things that help good images in a variety of conditions. Top end Sony small sensors fall in this range, used on LG phones and some action cams. I know it is hard to get them, but as a one off into the hobbyist market, somebody might be willing to supply as a promotion.

Have a look at this footage from an old 2015 sony sensor on the yi 4k+.

That is what can be done if the camera is setup good enough. This is not taking full advantage of the sensor as far as I know. I think that the sensor might have a her video mode, but usually you see native DR, which is still nice on the upper end Sony. HDR can produce issues when you push the stop range. So, a hdr mode on this camera might produce good results at 12-13 stops, maybe acceptable at 16 stops. But on high end cameras they tend not to push stood too much, because “acceptable” to us is not good enough for them.

A list of cameras, a list of things the reader has to figure out on their own and a single app to deal with it in the end. Sorry but this is prettymuch just clickbait.
