Similar to bug 240198, KDE Plasma still shows some wallpaper rotated in the wrong way. E.g., the image is marked to be rotated in portrait orientation and other KDE programs get it right, yet it is displayed across on the wallpaper background.
Interestingly, the blurred background that extends behind the wallpaper to the edge of the screen when the config is set to "Scaled, Keep proportions" is always rotated correctly, just the actual image is sometimes in the wrong orientation. (I didn't change any setting to have a blurred background behind the image - this appeared at some point in the upgrades to Plasma 5, where KDE 4 had a plain-colour background.)
Please attach a file that exhibits this issue.

Example picture file
This is an original picture file - the wallpaper shows the picture in the right orientation, but the blurred background behind the picture is rotated in the wrong way.

This is a screenshot showing how the wallpaper is shown - the main picture is rotated correctly, but the blurred background is wrong. Still trying to find a file where the picture is wrong and the background is right - but this is probably the same issue.
Maybe the problem is the blurred background not being rotated correctly? I found a few pictures where the wallpaper rotation is wrong, but the ones I found so far are also shown wrong in e.g. Gwenview - the rotation information was stored in a sidecare file.
But please look at the uploaded image and try to figure out why the blurred background has a different rotation than the image itself.
The blur is indeed missing the autotransform. will fix
