For anyone who has the same question as me: I have now found out what the difference is between the OLED55CX9LA and CX6LA models, and it looks like it's mainly about the triple tuner, which is not a purchase criterion for me. The CX6 has a single triple tuner, the CX9 a twin triple tuner. Here is the link to the direct comparison at lg.com https://www.lg.com/de/compare?bizType=B2C Hope I could help so many here!
