No, because the Mega Drive's graphics chip is "four years newer" and superior (for games) to the Amiga OCS ones (even if the Amiga OCS' 12bit-colour palette is eight times as big as the Mega Drive's 9bit-palette):

This is an improved version of the Sega Master System VDP, which in turn is derived from the Texas Instruments TMS9918. Images can be output at 256 pixels (32 tiles) or 320 pixels (40 tiles) across and 224 scanlines (28 tiles) or 240 scanlines (30 tiles) down. The 240-line resolutions are only used on 50 Hz (i.e. PAL) displays, as the extra lines end up in the overscan of a 60 Hz (NTSC) signal.

NTSC games use the 224-line resolution to free up more vertical blanking time to send more updates to the VDP. Colors are chosen from a total of 512 possible colors, 3 bits per RGB; some games used a small amount of flicker to simulate more colors. Graphics consist of up to 80 sprites on screen and three background planes (Window, ScrollA, ScrollB), two of which (ScrollA and Window) share the same screen space. Palettes are stored in color RAM (CRAM) and consist of 16 colors each for a total of 64 colors.[64][67]
