To a point yes. But also no.
Lighting changes in and of itself will change your image percpective for peep shooters and scope shooters alike.
A peep shooter can be worse off than a scope shooter though. If the sun off to one side or the other the sun creates glare on the peep and really adds to the problem. Most shooters will find that their POI will follow the sun throughout the day. When it is to the left, they will hit left. As the day goes on and it gets straight up, the POI will be centered and so on.
We are not talking about huge changes here but 1/2 MOA is very common.
