Image displayed in Lightroom has not the s to the same image displayed in Lightroom classic

Dear community, 

I have an image that I edited in Lightroom Classic on my desktop computer, then I exported it to photoshop for additional treatments and got it back to Lightroom Classic for final fine-tuning. 

This image seen in Lightroom Classic is displayed perfectly and with good quality. It is a .tif.

I added this image to one of my collection synchronized on the cloud. 

When I open this same image from this collection on the same computer but using Lightroom (Not Lightroom Classic, so the mobile app version installed also on my desktop computer), the image is displayed with a very poor quality. 

I don't have the same issue normally. Is it because it is a .tif and not a standard RAW file ? 

Thank you for your help.
