It could be a fake. USB 2.0 only requires 4 pins, but for the bandwidth of USB 3, you need the additional 5 pins.
However, make sure it doesn't have those five pins. They can be hard to see, and they wouldn't be visible on the angle your picture has.
On the female end, you have the five pins right up front, on the male end, you have the five pins shoved in the back. They're small and hard to see.
EDIT: According to telcoM, you might be able to technically call it USB 3, if it's getting some protocol improvements that can be applied to USB 2.0 and lower speeds. Can't say for certain if that's the case here, and it also wouldn't matter since it'd still be limited to USB 2.0 speeds.
So essentially, for most use cases, it's just USB 2.0, however it might have some protocol differences that technically allow them to call it USB 3.
