AFAIR, there is somewhere yet another flag that should be checked, which controls whether the graphics data is taken from RAM or ROM. Colour and brightness map access will be controlled by the ROM paging status in the upper memory area, IIRC. I.e. if they are at $8800 they will work correctly only when ROM is paged out ($FF3F), otherwise ROM content will be used instead.
