I think Plymouth tries to use the same resolution on all monitors. I'm not sure how that is chosen.
The attached photo looks like it's rendering a buffer that's higher resolution than either monitor and then can only display the top left portion. That will put anything at the centre of the buffer nearer to the bottom right of the screen.

Or it might just be a centring bug.
