I noticed something that probably is good but looks bad in my opinion.
I pixel peeped an image to compare the Jpeg vs Tiff. Both are exported with Lightroom from a raw file. I only changed the file type between the two exports. I know jpeg is set to max quality. I didn't see any settings, or didn't notice any that needed to be changed on the Tiff.
Looking at the dress on the inside where the black horizontal line is the jpeg shows a smooth skin, where as the tiff is more jagged.
Is this because it's higher quality?
I have tried to get the same "composition" on the two images and took a screen capture of it.
I noticed the Tif is cropped slightly so I took the Jpeg that is also cropped the same way. Nothing else is changed, no extra editing is done.
