How to prevent Windows make lock screen image darker?

First of all, I'm sorry in advance for my bad English and mistakes of rules if I had made.

Everyone know, we can go Change PC Setting => PC and devices => Lock Screen, then browse and click Choose image to make a custom background for lock screen. But we will have an image in background that darker than the original image, that is really annoying for me.
Example:
1.jpg
I'm sorry if it unacceptable because of sexy, but I want to use this image for you to clearly see how it dark.

Another way to make a custom lock screen is that we open an image by Photo app and choose Set as => Lock screen. We also have the same result.

Then I start thinking about it. I thought when we click on Choose image (option 1) or Lock screen (option 2), windows will run a process to copy and make the original image more darker, then stored it in a secret location. I searched that secret location on this forum. Finally, I found it in a place and as I thought, it really darker than the original. Here I knew what I thought was right. Then I only need to replace it with the original image. And my result below:
2.png
But in that way, I only resolved my problem by edit the result of a process that make image darker. So I continue face a new problem, about slide show lock screen. All of images in slide show mode was darker as I thought.

I'm pretty sure windows doesn't make whole folder darker, then stores all of it in somewhere as it do with normal lock screen mode, because I tried looking ".jpg" in drive C and don't recorgnize anything strange with the looking result. I think it also use somewhere to contain edited image, but only 1, then continuous have it replaced with shuffle image for next screen. So with the upper solution, I can't reach my purpose.

Sorry for my long post, but is there a way to resolve my problem without using 3rd software?

I had found something may be useful. Photo app have some functions to edit image such as Brightness, Contrast, Saturation... I think if we can make Photo app unable to use its functions to edit image, we can resolve this problem.

I hope someone can helps me or if it hopeless, please tell me some other forums able to help me. I don't understand much of English so I only knew this forum, every tutorial here was so friendly and easy for me to understand.

Update: I had found some wrong about what I thought. It not the moments when we click to set the picture as lock screen then the picture will be edited, it would be the moments when we press Windows+L to lock screen.
