SamyGO

I have a UN40H6203. With Some Samsung models I can modify the gamma curve with the 10p white balance. This tv doesn't have that option, the gamma curve after 40% drops to low meaning the brightness curve is too high. If I install SamyGo can I correct the Gamma on this set to BT.1886?

was the best I could get. 1.14de cie76(uv) y/ gamma. GCD clssic was 1.89de. Turned down the contrast to 80.
