i can't confirm. some tv are the same but have little changes like the wifi module etc. if you use that code, you can enable pvr probably but there are a lot of chance that he will disable wifi
so please, read the original code. fortunately yout tv is like mine (mine have same model number) and is fully supported by my calculator. open Github and search for "ToolOPT6" and you will calculate by yourself
In my experience you can enable "Support ATV DVR", "DVR Ready" and set "Sound Mode" to Dolby Atmos without any issue.
N.B. The code "541838600" is not for UP75 Series but it still a vadid code. If you put on the tv, you will disable "Digital eye", lost WiFi and Bluetooth functionality and disconnect all smart remote. Please don't do that
