Lightroom/Camera Raw: files lose details when you save them to TIFF

Hi! When you export a .tiff file from Adobe Lightroom/Camera Raw and save it as a .tiff, it loses quality. It doesn't happen with Adobe Photoshop. You can compare the original file with the exported one with the blend mode "difference" in Photoshop. After adjusting midtones in levels, it should be black if files are the same...

I saw this post this morning and thought to try to duplicate the results. but I couldn't. the image remained black.
In LR, I exported For eMail (Hard drive) an image Tiff, no Compression, Adobe (1998), 16 bits, 72 ppi. To a new directory.
Opened the same file in Photoshop. (Not the "Edit in Photoshop" from LR)
Now PS has 2 different tabs of the same image. I had to convert the LR version back to 8 bit.
then Duplicate the layer over to the other tab.
Setting the blend mode to "Difference" everything is black
I even added a brightness layer on top and cranked it to 150. Nothing. still black.

You're perfectly right if you use a brightness layer on top, but try to add a levels layer, that map every midtone, and set the midpoint to 9,99...i see a lot of pixels! My three files are tiff in sRGB, 8bpc and I'm on CR actually.
