First off, D65 is impossible on this phone without using Comfort View.
The best I was able to achieve (using a Konica Minolta CS-200 chroma meter, brightness at 50%, auto deselected) was x=.285, y=.325 (D65 is x=.313, y=.329), so I'm a little on the blue side. Here are the settings I used:
Screen Color:
Select Custom and hit the gear icon
Color Temperature: Cooler (slider all the way to the left).
RGB Levels:
Red: maximum
Green: maximum
Blue: MINimum
Result: x=.285, y=.325
If this is too green for you and you're ok with a little more blueness, decrease green until you're happy.
If you want true D65 white point, you have to use comfort view to filter out the blue, but then you lose your ability to use comfort view on a schedule. When you set comfort view to the setting just to the left of center, you'll get x=.313 y=.335, which is pretty much dead on (the slight green shift is pretty tiny). I did not yet measure the individual RGB illuminant values.
You will notice that these color values feel incredibly red or yellow compared to stock. You might not even like them. But they are technically more "white" from an sRGB standpoint. When I hold the phone up to my calibrated monitor, even the corrected version above looks incredibly blue. The comfort mode version looks about right. It will make your photos look more natural though. I have a photo of a sandwich that got more delicious after making these changes. Seriously, mouth watering.
For reference, the stock color profiles look like this:
normal: x=.276, y=.288
movies: x=.287, y=.300
photos: x=.287, y=.300
web: x=.286, y=.288
In all of them, the blue value is incredibly high. high blue will drive down both x and y coordinates. It looks to me like this panel is red-limited.
The color temperature was a bit unintuitive, but given the above red limitation, I think it simply removes green and you end up back where you started. Hence leaving it at full "cool".
So if you plan to take photos and want more accurate color when you do, try the above settings and compare the photos when you view on your phone to when you view on your computer monitor.
References: CIE chromaticity chart: D65 is 6500k on this chart. x and y coords are along the horizontal and vertical axes. You'll notice that x=.313, y=.329 cross at the 6500k point.
I've also attached some simple R, G, B, & W test images and a gradient.
