In conclussion (for those who dislike to read a lot, not me of course):
1- Eagle Vision is definitely a Precursor related ability and not a way of representing an Assassin's observational skills.
2- There are many types of Eagle Vision: Altair's (Default), Ezio's (available while running), Ezio's (mastered version also called Eagle Sense. It allows to "see" through time, watch past and future events". Also identifies the true nature of a person [Normal Eagle Vision cannot do this]), Connor's and Aveline's (identifies clues fast), Edward's (tag enemies), Shay's (tag hidden enemies and locates them), Arno's (short duration [who thought this was a good idea?]), and Frye Twin's (It evolves with practice).
3- It's not confirmed if Bayek possesses Eagle Vision.
Now, some theories:
1- The Animus Pulse could be a skill only available in the simulation, just like Evie's cloak or the Helix abilities in Chronicles (except the Russia chapter, in my opinion that was very stupid) whose purpose is to help us finding the collectible faster.
2- Bayek may not possesses "Eagle Vision" but another Precursor related ability: Telepathy with his animal companion, just like Falcon and his bird Redwing. I think he (Falcon, from the Marvel Comics) is the perfect example of this new concept and it can help us understanding it better.
3- This may be a new beginning for new precursor related abilities. Because, I don't think Bayek "controls" Senu, he sees through its eyes... telepathy is my best bet. Thanks to the bleeding effect and the requirement of needing a sample to simulate memories, this could allow us to control it without needing a blood sample.
