Ran some photoshop filters, nothing significant showed up. If I had to say I would say they are not shopped.
Sometimes through these filters you can see so e obvious differences/cutout lines but I couldn't get anything noticeable to show up
There was one funny little line but could easy just be the pixels:

The other one is seamless, even the little hairs at the edges etc, which is pretty hard to shoop clean imo
