I would definitely ask the dealer for an exchange asap, specifically concerning what you described as that "hot spot" on the upper left side of screen. That black dot clearly visible on the white test image, is that a stuck pixel or is it larger than a single pixel ? Did you put your face right up to the screen so that you could clearly see the screen pixel array and whether or not that dot occupies the exact same space as a single pixel or does the dot cover more area than a single pixel ?
From the picture it looks like the dot is larger than a single stuck pixel, which would be even more worrisome, but either way that is an unacceptable defect for any flagship UHDTV set, specially from Sony, and it worries me that QC at the end of assembly line prior to boxing/shipping would let something so noticeably unacceptable go through as acceptable. Someone on the Vizio 2016 P-Series thread posted a picture very similar to the dot defect on your screen and he said it turned out to be something stuck between the panel layers and that once he turned his set upside down whatever was stuck fell down to the edge of the screen and completely disappeared, problem solved !
As for banding, the camera pans too fast across the screen for it to be easily visible but i did notice some of it which i imagine it is more noticeable if seen in person right in front of the screen, as you pointed out.
Perhaps it is like the above poster described, a matter of Sony taking in as many of these AOU LCD panels as fast as possible to fulfill its initial production run on schedule and not scrutinizing them as closely as they should prior to full assembly ?
There are already people on the Vizio 2016 P-Series stating that both the Sony 940D and the Vizio P75-C1 use the same exact LCD panel from AOU (it would be great if anyone could confirm/deny such rumour), and if that is true, i imagine AOU would be manufacturing and shipping these panels as fast as they are capable.
I have been following both threads every day as i am planning on purchasing my set soon, but i also decided to wait at least 2~3 months for further price dropping and, more importantly, wait until production run is on second or third stage as i learned over decades of purchasing A/V electronics that it is almost always smart to wait past initial production run...
