Brushes/Effects being modified upon exporting.

[Guest]

Hello there!

I started playing with Lightroom and Photoshop once again after a very long break and I'm trying to get my head around all the features before starting to learn the professional ways.

Upon completing this rather basic edit, I noticed that the exported image is way sharper and a bit more vibrant than the RAW variant while still in edit. 

Export Method: Default settings besides 100% Quality - JPEG. Tried changing the resolutions and the profiles as well to no avail.

Both my RAW file and the export are sRGB.

Below you can find the comparison.

Please let me know if you need any more information!

Kindest regards.
