Problem with colors in the .psd file

Hi. I have a problem with colors in photoshop. I work in social media and I constantly use one .psd file (this is my template), which I edit and paste photos into it.

The problem I have is that when I place a photo in my .psd file, it loses saturation. In the visualization below I have provided an example of what it looks like:

- Number 1 is a photo of shoes downloaded directly from the Internet.
- Number 2 is a photo of the shoes pasted into my .psd file.

I place photos in the following way: file -> place.. (when the photo appears, its quality is already broken). Saving in different extensions doesn't help.

Is there any way to fix this? So that photos pasted into a .psd file do not lose saturation and have their original color? Thank you very much in advance for your help!
