I installed 04.70.36 with no problems and not noticeable improvement in performance (we do no use onboard speakers and the fix was intended to address an audio + HDMI issue.) You can go into the settings on the OLED to see what revision you're currently sitting on. Note that if you register your unit on the LG website and specifically look at Support for this model, you can get the entire history of updates and what they address. From this site: Release History [03.51.20] 1. Improve the backlight turn-on failure [03.60.09] 1. Improvements in HDR (HDR 10/ HLG) 2. Bugs fix in Dolby vision 3. Improvements in shortcut key for apps on remote controller. 4. Improvements in Dolby Atmos (the B7A doesn't have this anyway) [03.60.15] 1. To improve T8 store stream equipment issue. [04.70.07] For 2017 OLED TVs (W7, G7, E7, C7, B7) 1. Support TrueHD audio format through HDMI 2. Technicolor Expert mode [04.70.30] 1. To improve Dolby HDR HDMI True Motion Off Condition Screen Breaking Issue [04.70.36] 1. To improve OLED model Dolby no audio issue when switching HDMI input
