Yeah it's 100% gyro strips. I've had them in gyro kits before. While they have a less saturated color like spam or other processed meats, I think the lighting angle in this picture distorts it a bit.

They can be really greasy so that's what the light is reflecting. I dab them with paper towels when I prepare them.

Normally it's not served plain, obviously. Usually it's on a round peta with onion, lettuce, tomato, and cucumber sauce.

Edit: Here's an example of what I mean. Sometimes the cheap, hyper-processed stuff doesn't have the frilled edges that most people would expect from "off the cylinder" gyro meat.
