The first one is from SeeMusic Piano, the picture has a darken keyboard while not darkenping his hands, and only also beautiful LED light are shown on keyboard.
The SeeMusic app provides the "Add Light to Video" feature that can blend the in-app lights with your video footage, to simulate the effect of having an LED strip on the keyboard. Many users use this feature for their videos instead of using a real LED strip.
However, there's no way around the fact that if you want the light to create shadows on your hands and the keys on video footage with your hands in it, you would need to use a real LED light strip during recording.
