Hi Synn,
The lens I used for the large tree trunk was shot with the Hasselblad Zeiss 100/3.5, it is known to be one of Hasselblad's sharpest lenses. Hasselblad compares this lens with the HC2.2 100/3.5 at infinity here:

On the other hand, I have shot my sample on the A7rII and it performs really well, it outresolves the Sony sensor and it is a good match for the Sony 90/2.8G.
I have also developed the P45+ image with Capture One 9.0.2 using default sharpening, it oversharpens quite a bit, check the enclosed MTF. MTF between 0 and 40 lp/mm exceeds 1.0, which means oversharpening. LR 6 is nearly ideal in this case. But LR 6 has a lot more colour aliasing than C1.
These shots were about finding out the lens and all shots were at approximately at 50x focal length.
John Lytton has also posted a comparison, using a Canon 5DsR with a Sigma 70/2.8 macro and a Zeiss 120/4 APO Macro Planar, with a Contax 645 and an IQ160. He also found those images similar.

Best regards
Erik
Sorry for technical stuff, I know you dislike curves and technical discussion, but being an engineer I find that a curve says more than 1000 web size images.
So I enclose and image that is utterly irrelevant in the context but has been take a few hours ago:
It has a lot less to do with the sensor hierarchy than what's in front of the sensor.
I have seen much sharper images from the P45+ mated to a more modern body and lenses than what Erik usually posts.
Not a knock on Erik, just that when you use legacy gear, expect legacy results.
