This is my 40pin gba (cpu-04) vs my cpu-02 gbc (so they are both early revisions), they are about the same reflection wise i find, gbc might be like 5% more bright but its not much.

Only big difference i notice is gbc has a more neutral white, but it doesnt change much.
It's very possible that you have a gba screen that is inferior to mine, whether its because of 32 pin, or a panasonic panel, or just an inferior panel just because.


It's also possible that gba graphics are more complicated, and colours generally less pastel than the gbc it works worse as a reflective display, the simpler graphics might be easier to perceive on a sometimes dull reflective screen, and the brighter colours will make the gbc effectively brighter. It's food for thought. Apparently the gbc also has multiple screen revisions but i imagine they got better as time went on that worse unlike gba
