It would tally with what I'm seeing too, only I'm seeing it through what I think is contrast as well. Blacks have always been really good for me to my eyes, so perhaps I'm overlooking things.
The basic measurements I could perform did not show any differences between firmwares.

Dark environment was impossible so I used the K10 in the contact mode. Some light was slipping through the glass yielding MLL of 0.002 Foot Lamberts. In the dark it would certainly be lower and I will have some dark time with this set in mid July when it gets a tuneup.
Did some testing with both FW 1017 and 1104. The CAL modes were not enabled until after loading 1104.
Both pre and post FW 1104 gave the exact same results:
1 0% = .002FtL
2 4.8% = .002
3 9.3% = .003
4 13.7% = .005
5 20.4% = .011
6 24.8% = .015
7 29.3% = .016
8 33.7% = .017
9 38.1% = .018
10 51.3% = .02
11 61.6% = .02
12 72.8% = .02
13 87.5% = .02
Sorry - forgot all about the below request and will get the measurements next time in a dark environment
1. Black optimizer dark room, Cinema Smooth off, Peak white ~45 ftL (pre-FW update)
2. Black optimizer dark room, CS off, Peak white ~45 ftL (post-FW update)
3. Black optimizer dark room, CS on, Peak white ~45 ftL
4. Black optimizer bright room, CS off, Peak white ~45 ftL
5. Black optimizer off, CS off, Peak white ~45 ftL
6. Black optimizer dark room, CS off, Peak white ~30 ftL

you get time, it would be great if you could test the fL on a Windows 100% (not APL as that's not what was used by the OP);
Cell Light 20
Color Space Auto
10p White Balance - required? - its really pushed on 9 and 10.
That tested peak white 41.2FtL with Accupel APL Windows patterns.
I didn't have time to input your lastest calibration but I used the above numbers for the "After" measurements in the following report. For the "Befores" I changed Cell to 18 and Contrast to 94. 2 point GS was set to default, 10 point OFF, and CMS Auto. Then I did what all owners can do - used Test Pattern 1 to set Brightness and got 47, then used Test Pattern 2 in the Blue only mode and came up with a Color setting of 52. This measured peak white of 47FtL so you can see how much your Contrast setting of 82 pulled luminance down. The Before and After measurements produced a tie ball game which supports what all calibrators know - copying someone else's settings is a 50/50 chance of picture improvement with the exception of 2 point Grayscale because most TVs come from the factory with overly blue GS so a reduction in 2 point blue and a possible slight increase in red can help quite a bit....

The F8500 calibrates well:
BautschF8500 CAL-DAY AdvancedColorManagementReport_AVS.pdf 370k .pdf file
The problem with Grayscale in the upper levels was evident in this display, especially 80 and 90% stimulous. pieandchips, looking at your numbers above. 90% was problematic:#8 1,0,-2
It's not worth any more than small changes when increasing the adjustment does so little. Something is wrong and needs to be fixed. The top end of the Grayscale on my fishing buddy Dave's F8500 was pinkish.
@LarryInRI & zoyd
Help me out here. Calibrating 10% as a single entity produced a good result:
but when doing the post Cal Grayscale run, 10% measures poorly. Something is happening when going from full black to 10% stimulus and I suspect this might be happening in moving video as well:
1. CAL modes enabled, Cell 20, Contrast 100
Movie mode, Field Pattern, 20.1 FtL max luminance. APL pattern, 56.4
CAL-DAY, Field, 21.2, APL, 56.7
These numbers are the same as Movie prior to enabling the CAL modes.
2. If you're sending PC level RGB to the 8500, be sure and select HDMI Black Level Low. MLL LOW = .002, Normal = .129
3. The CAL-DAY I used was Cell 20, Contrast 94, Brightness 47, Sharpness 0. This produced 49.511 Foot Lamberts and was a comfortable luminance output for the fairly bright room in which the Samsung is located.
The reference content that I use looked excellent. This is a display that would keep me happy until a better technology comes along. You owners enjoy your TVs. You make a great choice.
