Nah, just folk who look closely are typically able to notice they perceive shades of colors slightly differently. Everyone I’ve tested it with has been able to do it.
How do you test this though? The eye is highly adaptive. If you close one eye, look at something red, then close the other one, your formerly closed eye will already have adapted to the darkness of your eye lid. Depending on how long you do the looking, I can imagine this leading to quite a difference in color perception already.
Looks the same to me, do you have some kind of source or paper to back up your claim?
