We should also keep in mind that these are Bayek's genetic memories that someone is reliving through the Animus, if Bayek could not actually see through Senu's eyes, then neither could the person reliving his memories.

Unless someone is suggesting that the Animus also has access to Senu's genetic memories through one of his descendants, I think it's safe to say that this is an actual ability that Bayek had.
