I was going to chime in a while back when I saw these on the mobile, but got distracted in other posts (and working...).
My first and considered reaction is that the original posted images are not to my taste, but you have got some clean separation between tones.
Now I'm going off sideways again. LOL
I'm really not sure if this is a concept that's difficult to understand or if I'm just not explaining it very well. Things are not absolute.
Excuse the diversion, there is a point...
Look at the snow on the mountainside in sunlight. It's white and bright. But look closer, the shadowed snow is not white at all, in fact it's not even grey but blue. Lit by the blue sky shadowed snow has not only a distinct blue cast but is noticeably darker, yet when we stand in the valley and look at it we instinctively know it's white.
There you have in one vista two distinct tones and colours that we see as both being white.
There is also a really good optical illusion in greyscale, I think it's a striped cone part sunlight and part shade, where exactly the same shade of grey looks noticably darker in one part than the other simply because we perceive the lit part to be brighter than the shaded.
The same shade of grey being interpreted as two distinct tones in the same vista.
Now look at your hostas before you took the photo. We look at one leaf and instinctively understand that they are all of similar colour and tone. But look closer, just as we did with the snow... They do not all possess the same tones, some are darker than the others and we just understand them as being the same.
This is one thing I do not understand with digital photography, why do we feel the need to edit our photos in such a way as all the leaves
DO have exactly the same range of tones? If you see the different tones in the real leaves as being the same then surely that also works in a photo?
Look at your monitor. The white is nowhere near the brightest thing you've seen, (the snow on the mountainside in bright sunlight?), and the black is nowhere near the darkest thing you've seen. Yet you still see the tones as black and white.
Hell, if you looked at exactly the same picture on a monitor with less contrast than yours you'd still see the tones as black and white!
Things are not absolute.
Black and white is just a relative perception of lightest and darkest.
So in your image I see the perception of the tones as being the same as if you've used the digital editing tools at your disposal to push the contrast of each leaf towards the maximum and minimum tones that you have available:

Now seeing as in real life we understand that even when the leaves have a different scale of tones that they are in fact all the same, what would happen if we presented an image that showed just that:

Would we see them as different in a photo or understand that they are the same? What would happen to our perception of depth in the image? What would happen to our impression of light in the image, would you have a greater impression of light just because brightness is not so uniform across the image, and actually there's more dark?
Here is my edit of your edit, and not how I would've edited the original. Not as a definitive correct way but just as a variation. Download them an look at them in your chosen image viewer, but look at each for at least 30 seconds before flipping so you see each image and not just the differences:
