Although there are very few examples in Cyan ages where bump map images (the textures are named "...bump...", not "...normal..." - although they look like normal maps (colored) and not bump maps (greyscale)) are included as textures (e.g. the shores in Gira water, or the walkway in Kemo), I'm pretty sure that normap mapping is possible in Plasma. At least bump mapping.
There are real bump maps (greyscale) as well, e.g. in the City district textures (for Ae'gura), used for stone surfaces. But, really a few only.
But I guess PyPRP does not support including them currently.
It may be able to use them by patching the final PRPs with other tools though (PRPShop, PRPExplorer etc.).
EDIT: (Although, when I read Paradox' post, I'm not very sure any longer - could be a mess to play with these tools to get everything in the right order).
Oh, and the difference:
