No, they are universal. Any 3d blu ray player will work.
Last night, as we were watching TV from our breakfast table (about 15+ feet away) my wife got up to retrieve the remote off the couch. As she did, the TV picture dimmed and went back to normal as soon as she walked back. Since everyone saw this, I got up and did the same thingand again, the TV picture dimmed. Standing to the side of the TV, I placed a sheet of paper in front of the power light, and the picture dimmed again. Bottom line, the standard picture mode adjusts picture brightness based on room lighting. THX mode does not seem to do this.
