Thought I would post part of the post-calibration report. Looks much, much better. I'm happy. He also created a profile for night viewing, day viewing and gaming.
"The main areas of improvement after calibration were gamma tracking (consistent brightness moving up the grayscale curve), and color gamut accuracy.
The pre-calibration grayscale had relatively small errors but they were mostly plus-red errors, which are problematic, even in small degree. Post-calibration grayscale was very good, with virtually no error across the board (note, the errors shown at 10% are hardware measurement errors, and these levels were double-checked by eye).
Gamma improvement was significant. Basically gamma is the brightness of the grayscale as it moves up the curve; like every other aspect for grayscale, there is a standard for how bright the TV should be at each measured grayscale level, based off the maximum brightness. Well-behaved gamma creates a smoother, more natural-looking images, particularly in images with mixed lighting levels (bright and dark areas adjacent). The color gamut improvements were also very helpful, and you can see the main differences in the Delta E 1994 graph (the goals is to have error bars of 3 or below). Of course, that wasn't possible with the Red primary, due to the red primary saturation issue that is well-documented in reviews and online".
Edit: I forgot to add that he has 12 years of experience and he made small adjustments by eye afterward to fine tune it a tad better. (Actual picture versus calibrations screens).
FWIW, I have TV, Directv HR-24 DVR and Xbox One plugged into a Yamaha RX-377. Use one HDMI cable to the TV. The other devices are fed into the receiver.
I'm quite pleased with my budget setup.
