The low-contrast look has been fashionable for a long time, since people started shooting in LOG and then editing in it and getting used to how it looks. Colourists talk about this problem like it's been around for many years and simply never went away. This caused a feedback loop where directors fought the colourist to keep things bland, which made films get released with bland grades, and then this became the reference for future directors and also all the amateurs.
Also, it's quite hard to add contrast in post because it requires a clarity of thinking that many do not possess. When you look at your image and see it's captured all this information in the shadows and highlights and then apply a healthy level of contrast you immediately miss the details that are now crushed in the rolloffs. This leads to the question of what parts of the scene can be obscured.
The only way to be able to answer this question is to understand what the shot is about, and therefore what is relevant.
This is a level of maturity not yet attained by many.
I didn't really do a systematic comparison with the G9ii, but in general terms, why would I pay several thousand dollars for a new camera that isn't the leading offering, when the flagship is only a few hundred more?
Certainly, if internal Prores and cooling fans were absent on the G9ii then either of those would probably have been an instant disqualification. The size comparison is pretty moot as well, for street work I'd consider both to be full-sized bodies.
