Oh, I did not use the 45 point autofocus. I only used the single center point autofocus. I should change to the 45 point autofocus? That doesn't sound right.

I have a brand new 80D and I have the same viewfinder vs. live view focus problem. I think it's the camera. These images were shot using a tripod and timed (2 s) shutter release. My hands did not touch the camera when the pictures were taken.
One shot, single, center point autofocus, 24mm, iso 400, f 2.8. It's a little hard to see, but the top image was autofocused through the viewfinder. The bottom image using live view. My old Rebel T1i takes better pics. Guess I have to send the camera in for warrenty repair. Very disappointing, brand new $1100 camera.
It appears that you may need a bit of autofocus microadjustment. But if you're going to rely on a 2-dimensional test pattern to do the calibration, make sure that the pattern is absolutely perpendicular to the line of sight. In your images, it appears that the right side is in slightly better focus than the left, suggesting a slight deviation from perpendicularity.

Posting photos with EXIF data is useful. Screenshots are totally useless for evaluating the focusing ability of the camera.
