Adobe settings to Camera settings on pictures already uploaded

Hello,

I found out a few days ago that my LR waq set on the Adobe settings colors for months. I now understand why the pictures looked low quality when uploaded. 

Anyhow, I changed the settings and it fixed the image quality issues I had. 

But now... Can I change back the pictures that have been already uploaded to LR to switch from Adobe profile to Camera settings ? How ? Thank you
