This question from 2020 suggests the answer: Image Capture uses lossy JPEG compression inside TIFFs captured with a rotated bounding box, but lossless LZW compression if captured with an orthogonal bounding box. I find this utterly bizarre and inexplicable, but there it is.

I suppose that if one wished to save a rotated scan with lossless compression, one would have to save it in PNG format.
