Calibration report using these settings:
[see post below]

TV software/firmware version tested: Oct 22 2013

Below you'll find the settings I found best for viewing the Toshiba 65L9300U in a dim room via the HDMI input. Your settings may vary depending on source, room conditions, and personal preference. Check out the Picture settings and calibration FAQ for more information.

Calibration notes: Prior to calibration the set's Movie mode measured worse than most high-end TVs I've tested, hampered by inaccurate gamma and too much light output. The controls helped change the latter but were unfortunately too limited to do anything about gamma.

Toshiba's local dimming is controlled via DynaLight, which only has two settings: On or Off. The former results in significant black level improvement, so I used it for my calibration.

I also altered my calibration somewhat based on how DynaLight behaved. The circuit Increased light output with high APL scenes quite a bit more than normal (a full white raster measured a whopping 37% brighter than a window pattern), so to compensate I reduced the target light output of the window pattern from my normal 40fL to around 35. That reduced the effect somewhat, and also helped black levels.

According to my charts my 10-point grayscale calibration corrected the gamma to be almost completely linear and nearly match my 2.2 target. Unfortunately to get there I had to dial a few of the controls out to near the limit of their ranges, and afterward noticed the same kinds of unacceptable artifacts visible on previous TVs I've adjusted "too far." They mainly appeared as false contouring in areas like the color fades of the PS3 menu system. The Toshiba also didn't seem to hold a 10-point calibration very well at all. After a 10-point calibration at the end of one day, I took another the next and it was very different.

Resetting the Movie mode to its defaults fixed the issue, of course at the expense of ruining gamma again. I chose to go with the contouring-free, too-dark near-default version, which is why the 10-point settings show no adjustment. I was able to improve it somewhat by maxing out the bias controls in the 2-point system, which didn't introduce any artifacts I noticed.
