Issues with Shadows in Modules and Exports

[s.vaidy]

Hello!

I've been having this problem with Adobe Lightroom (Classic) on and off, but it's now become more consistent issue. The shadow values are being crushed or flattened out into a grey-ish tone. At first I thought this was a screen calibration issue, and when I sent an image from my computer (a 2020 macbook pro) to a friend's freshly calibrated screen, it looked pretty bad. But the problem persisted even after I calibrated my screen and then sent another test image. I'm nervous that it's an issue with my entire catalogue, because even when I set my profile to Adobe neutral, all the shadows looks strange. The difference is even more apparent when swtiching from the Develop module to the Library module. I think this goes a beyond a calibration issues. I've attached some images as a comparison. If anyone can see it, even just slightly, and has a solution, I would be extremely grateful. This has been really affecting my work as a photography student and I want to fix it. 

Thank you for your time.

To make the problem easier to see, I combined the two screenshots into a single Photoshop TIFF, auto-aligning the layers (attached).  In Photoshop, enable and disable the top layer to see how it differs visually from the bottom layer.

1. Such differences are more often than not caused defective display profiles. To rule that out, try temporarily setting the display's profile to a known, built-in profile and then restarting LR, as described here:

If there is then no difference between Library and Develop, that points the finger at your current display profile, and we can go from there.

2. But if the difference remains, the problem is elsewhere. Please do the LR menu command Help > System Info and copy/paste the entire contents here so we can see exactly which versions of hardware and software LR thinks you're running and important LR options that are set.

"Though, while it fixed it to a massive extent, there are still tiny aberrations I notice. "

If you zoom both Library and Develop to 100%, do you still see those small differences?  Very small differences are to be expected, since Library and Develop use different algorithms to display images.  If you see differences at 100%, please post full resolution screenshots.
