I have a 30051 instruction booklet with a blue background like set 30052 instead
of the red and white version shown in the stock photo.
Is it an error? Or a rare version of the set like a "blue box" version?

Neither. It is just an updated design that was used for later production runs
of the polybag set. The red and white version is the 2010 design, and yours is
the 2011 design.
