You only need to reinstall the graphics sub-systems when you change GFXBOARD or SUBGR. 'inst' cannot differentiate between the Indy with 8 bit graphics and the Indy with 24 bit graphics. The inst man page indicates,
Graphics board: Indy *-bit IP22 NEWPORT NG1
that is, indicating that the GFXBOARD and SUBGR are the same no matter have many bit planes you have on your Indy XL graphics.
