Isn't 12 MP way past 4k resolution anyway? IIRC "4k" means 3840x2160, which is only about 8 MP.
16-20 MP on a 12 MP sensor should perhaps be termed "digital zoom" as they are literally inventing information (aka interpolating) to come up with more pixels.
FWIW, I think you are right about some software sharpening happening.
I know that with the Viofo A129, the fellow who makes modified firmwares addresses sharpening. He offers different amounts of sharpening according to user's needs. This is apparently due to variations in the optics of the A129 cameras.
I have been running with "standard" sharpening, since as you say too much sharpening reduces image quality.
