True, name calling is wrong no matter what. I feel no need to apologize, I do not thnk I acted improperly anywhere in this thread.
Taken in the context of the original photos by the OP, though they may consider it serious, in the end, it is likely nothing more than a 90% chance of user error or perception, as that is where the odds are.
The bottom line is that one cannot realistically compare an obviously well post processed shot of a car from a distance to a less well post processed shot of a flower at a much closer range and then say something like sharpness is decreasing and ask for an answer why.
How could anyone here without doubt hand over the one single correct answer without guessing? They cannot, there are just too many unknown factors starting with the user to hardware and software.
