That's not true. Modes 3 and 5 are paletteless, and can display all 32,768
colors, or rather Mode 3 can, because Mode 5 doesn't have that many pixels.

Quantum Mechanics are God's way of making sure we never really know what's

Subject: Re: [gbadev] Converting 32k colors images




the gba is able to display 32k distinct colors, but unfortunately it
can only show 256 of the 32k different colors at the same time. The
limit is not the gba's ability to show colors, but that its palette
memory is only 256*16bit large.

I hope this is helpful.
