How does the fact that we have to stand in the press limit the angle our body can take in relation to the bar (assuming a rigid torso)?
How does the fact that the press is a push and not a pull (specifically a partial row in the case of the chest to bar pullup) affect the mechanics of the lift?
Before you posed these hypothetical questions, did you look for quality pictures and videos of strict chest-to-bar pullups?
The answers await you.
