The sensor actually has absolutely nothing to do with sharpness beyond the choice of OLPF which is very minor. The sensor is not the culprit of an image that is not sharp. You can put a garbage lens or an amazing lens in front of a 1" sensor and get the predictable results. The sensor also has nothing to do with the bad color (which isn't that bad IMO), that is entirely the processing and you can control all of that in post.
Your image settings look OK based on the EXIF data.
Were you trying to pick the focus or did you lock it to infinity?
The first one looks slightly out of focus, the boat area (what I imagine is the subject) is pretty sharp, but the whites are blown which is not the sensor's fault.That second image actually looks quite good at 100%, but is underexposed by probably 0.7EV which isn't helping anything.
I'm also guessing those are straight out of camera JPEGs rather than processed RAW files, so you are at the mercy of DJI's JPEG engine which is not nearly as good as what you might be used to with other cameras like a Sony RX100 1-6 or Nikon 1 series that share that 1" Sony sensor.
What you need to do is some controlled testing. Can you also post some samples (at similar distances and camera settings) with your other 1" sensor cameras that you think are a lot better?
Also if you're scrutinizing the corners, a lens that wide is not going to have perfect corners. I have $2,000 DSLR lenses that don't look much better in the extreme corners.
I'd suggest not giving up yet - at least not until you've done some controlled testing. And don't expect it to put out the same image quality as something like a Sony RX100 which has a much better lens. The still image quality from the
M2P is exponentially better than the Air or original Mavic Pro.
