Laser Blue and Deep Blue Pearl are similar colours but two different colours. The DBP is the R32 colour, my understanding is that they discontinued the LB because it was too similar to the DBP.
You do get LB GTI's here that are not imports, you just don't see them that often as they stopped making them a year or so after the mk5 GTI came out, so quite rare.
Quite often see early mk5's (not GTI) in LB though, very nice colour.
