Increase contrast ratio on 2015/2016 Sony TV's

Sony seems to be shipping their TV's panels with a very low contrast ratio by default, even when you push the contrast up to 100.

On the 3 2016 Sony TV's I played with, I was able to get a improvement of around 800:1 over the defaults.

Step-by-step:
1. The first step is to switch to "Graphics" mode & reset ALL the settings (including the 10pt controls)
2. Turn the Contrast control to 100
3. Next set your pattern generator to a TV legal signal (16-235)
4. Power off the TV
5. Press Display, 5, Vol+, Power
6. Go to the White balance menu
7. Increase the RGB Contrast controls until you get clipping on your desired color temperature (I recommend using free measures on HCFR and the Near White Measurements feature)
8. Press the back button on the remote until you get to the Main SVC menu
9. Now Press Home and switch back to your HDMI Input
10. Power Off and on the TV
11. Reset Graphics and Expert1 again
12. Do a 10pt measurement run and set your Gamma offset. -1 and 0 will most likely result in color clipping (I ended up with -2 for 2.2 and -3 for 2.4)
13. Go to Point 10 of the 10pt Gamma adjustments and increase it until you get clipping again
14. Start at Point 1 and Flatten out your EOTF (gamma)

Notes:
• There should be no reason to write down the default Service Menu WB controls as unless you've had your TV serviced (ie. Panel changed) they should all be set to "512"
• Do not touch the 2 Point controls after doing the service menu WB as you will loose some contrast ratio
• Do NOT touch the Black Level controls in the service menu
• Point 8, 9 and 10 mess with eachother, it might take a few goes to get them to behave

End Results on my X800D (in Graphics Mode):
• Factory Default, Contrast 90: CR 2948:1 [White=318.02 cd/m2]
• Factory Default, Contrast 100: CR 3502:1 [White=393.99 cd/m2]
• SVC & 10pt WB, Contrast 99: CR 4198:1 [White=478.04 cd/m2]

My XBR-43X800D calibration settings (Do not copy them, they won't be valid for your TV)
