I would not be surprised if the data they found and interpreted incorrectly was "10 bit lookup table". You do see this specified for some panels. It simply means it is a 8 bit panel and uses a "lookup table" to take incoming 10 bit data and convert it to "correct" 8 bit data for display (i.e., it will display incoming 10 bit data--it just displays it as 8 bit).
Granted the above may be BS; however, I seriously doubt that anyone on this thread would "bet their house" on the fact that their 8550 or 9000 is 10 bit.
I think a lot of the confusion actually comes from the replacement parts on Samsung's Part site. The 8550 has two replacement LCD parts; One is an Open Cell which would need more parts to complete and it is listed as 8-bit. The other is the whole shebang and it is listed as 10-bit. The HU9000 on the other hand only has the 10-bit listed. Regardless I would not bet much on whether or not they are 8-bit or 10-bit. Parts catalogs can be wonky.
On the other side I think when we ask a Live Chat Rep a leading question like "Can you tell me if my tv is 8-bit? They will look, see nothing and say "Yes" because that is the answer the consumer seems to want. Or as you pointed out "Is it 10-bit" they will see that lookup table and say "Yes".
