For those who have tried, worth it ba? TIA
I calibrated my own LG OLED C1 since I already have a colorimeter for my PC monitor. I had to shell out of a 1-year license for the Calman Home LG software to calibrate each of the display modes of the TV (SDR/HDR/DV/Game Mode HDR/Game Mode SDR), which is also a time consuming process.
For me it's worth it because I'm already used to consistently color accurate displays and to my eyes, I get bothered when the colors are off especially for the skin tones and shadow details.
For most people, I would guess that the accuracy of the factory calibration for the industry standard FILM MAKER picture mode with some tweaks for personal taste will suffice so professional calibration may not be worth it.

I just saw HDTVTest's review of the LG C4 OLED and I'm actually tempted to upgrade to this. The new model now has an MLA panel and the peak brightness can hit around 1000nits, plus it has a 144Hz refresh rate mode.
