It is, although the visible part doesn't change all that much.

Here are the steps with a real 16 bit image. I've also included the
tux, which gets added as the usual BMP, so if you look very carefully,
you can see that its immediate background differs a bit from the
surroundings.

SVN: developers/werner/splash
  ./imghs.pl >out

openocd:
  halt
  load_binary wherever/out 0x32000000
  load_binary wherever/splashu.bmp.gz 0x32096000
  resume

u-boot:
  nand erase splash
  nand write.e 0x32000000 splash 0x98000
  setenv splashimage nand read.e 0x33d00000 splash 0x98000
  setenv bootcmd bmp display 0x33d96000 185 475\; ${bootcmd}
  saveenv

Note: you have to reset "bootcmd" to some reasonable default first,
i.e., one that doesn't already include "bmp ...".
