I put some time in this test comparing my iPhone 16 pro max capture to my Nikon D810 through a Nikkor Micro 2.8 lens -- the Nikon was locked down on a heavy professional bogen tripod and I was using a wireless remote shutter release.
the iPhone was hand held, I am quite practiced hand holding shutter releases, but that handholding the iPhone is a flaw to my results -- I do believe I got the leaf surface in focus -- if I used the iPhone processing it looks much sharper (but way over sharpened for my taste)
the iPhone was shot yesterday, I went back same time this morning with the Nikon
here is the iPhone full frame:
I shot Apple RAW format
Opened in Photoshop in ProPhotoRGB in 16-bit
I did minimum selective color (it could use some more minus yellow saturation)
did a little unsharp mask (sharpening)
converted to sRGB
Down scaled to 2000 pixels tall (hoping it fits forum size)

below is the Nikon version -- I shot the Nikon loose (4912x7360 pixel dimensions) and cropped in
I shot in RAW .nef
opened in Photoshop ProPhotoRGB 16-bit
I did minimum selective color
Slight Curve adjustment
and a little unsharp mask (sharpening)
converted to sRGB
Down scaled to 2000 pixels tall
you may notice the Nikon example below goes slightly soft at the bottom -- this does not ruin the image for me as the shot is in the fat part of the leaf (I shot this at f/8, I probably would have tried f/11, but the light didn't last long)

CONCLUSION:
these results are pretty much what I expected -- the Nikon has Nikkor glass and the ability to stop down, I am not sure if this Nikkor is a so-called Flat Field focus lens
here is the original scene -- you may be able to see what I saw when the sun backlight hits the leaf -- the magic happens...

if you want to bring these images into Photoshop -- sRGB would be the correct profile to Assign...
