I see the words "WE LOVE YOU" in the negative space in the first video.
The bottom is definitely covered with repeating non-letter shapes.
Edit: You're right, the text is only in the middle and next largest "fold." The rest is, spoiler, alien face glyphs.
Indeed the regular pattern can be seen as alien faces. But they are so close by that to me the slanted "eyes" and the cup-like "chins" more readily form plant shapes, with pairs of "leaves" and "flowers" above them instead.
