What did you do?

I opened the TIFF in Pillow and converted it to JPG.

What did you expect to happen?

The JPG image to look the same as the original TIFF.

What actually happened?

The converted JPG looks malformed and has messed up colors.

What are your OS, Python and Pillow versions?

• OS: Linux
• Python: 3.10.5
• Pillow: 9.1.1 (also tested -git)

>>> img = Image.open("3662b8bd397337482862ab1a06bf3366-OA_535_161_17_F_TE.tif")
>>> out_img = img.convert("RGB")
>>> out_img.save("converted.jpg", quality=95)

original image (beware, 274MB)
converted image

Is it okay to report this here or should I report this to the appropriate library (libtiff, jpeg-turbo, ?)
