Interesting thanks, how did you mod it?
Well the caveat is people say it breaks your warranty, but you just got into the service menu and there's a specific panel type
With a service remote I accessed the service menu.
Under Option & TypeI had a 55A40UGOC (S95C panel)
which means it is compatible to be changed into an S95C.
Other model codes are likely S95B panels.
I changed this to 55A4OUSOC (S95C code)
I backed out and then turned the TV off for 10 seconds.
I turned it back on.
Brightness goes from I believe 200/1100/1100 to 280/1400/1400
you can also turn off auto back light dimming and some other stuff, but at your own risk
