You may have noticed the numbers on the fruits. Those correspond to samples I have read with my ColorMunki Photo spectrometer.
I have added most of those samples as a layer on top. Choosing mixing mode "color" overlays the color ignoring the luminousity, I think.
Here is that link:

What I can see the Habeneros 3 and 4 show the largest deviations.
Please note that some colours are outside sRGB.

Note! Below is some new information...
This is a colour test. Please don't try to mix focus, DoF etc in the judgement, it will just be missleading.
Just to explain, the original ideal was to see how a set of reasonably well defined colours would map to Lab colour space using different profiles. The results were "all over the place", so I gave up on interpretation.
Here are the details how the images were made:
- Obviously all images were shot with three cameras from similar angle of view.
- Focus is different between the images. Focus doesn't affect color, so I strived for decent focus but it differs between the images. Forget about focus. This is a colour test!
- All images were processed in Lightroom, with the DCP profiles I use with each camera. Those DCP profiles are all created with LumaRiver Profile Designer.
- White balance was set on second brightest grey patch on each image.
- Luminance channel was set to around 51 on fourth brightest grey patch. That is the reference value for the Xrite ColorChecker.
- The images were exported at 1500 pixels width and opened in Photoshop.
- Each image was resized to 1500x1050 size. copied and pasted as a new layer in the image.
- All the layers have been aligned. That adds distortion in the mix, but makes it easier to compare color.
- The layers were copied as individual pictures from each layer.
Here is a layered image:

Mucho discussions about Colour on X1D or GFX. I have neither...
But I have shot three images under controlled conditions, generated DCP Colour Profiles for each camera and processed the images the same way.
Two of the images were shot on Sony cameras (A900 and A7rII) and one P45+.
So, can you tell which one is the P45+
Notes:
I have reworked the samples, to make sure I made no mistakes.
