Few thoughts:
There are select buyers for these sizes in Indian market hence we do not get to see many reviews or experiences shared. BTW LG has also listed the 97 inch G2 on its Indian website as coming soon (will be Made in Korea- imported model like the 88 Z1/Z2).
97/88/83/77 sizes are significantly high cost compared to US or UK market as they are all imported in our country and considering the duties/taxes applicable here. 83/77 C1 were imported from Vietnam. 83/77 C2 were imported from Indonesia.
Price is also determined by competition, e.g. Sony does not offer a 83 inch option in India hence LG can decide the price. Panasonic has recently launched a 55/65 inch model, but their pricing never makes sense. They also dont launch their flagship models in the country. I owned a 65VT30 plasma TV till it developed a panel problem - vertical lines (was Made in Thailand model). I was interested in buying their 65FZ1000 in 2019 but lowest price i got was 2.24 lacs. I ended up buying C9 for 1.77 approx after Cashback and with Home theater bundled.
Thing to note is that LG eventually sold all 83 inch C1 models in India and now the C2 has also seem to be running out of stock. Last price available for both models was approx 7 lacs (MRP 12 lacs). It may take few years or when local manufacturing starts for them to make these sizes similar/lower priced to Western market or Vietnam (MRP of 83 C2 is 4.88 lac on vietnam website).
I do own a 83 inch C2 bought last year October 2022, upgraded from a 65 C9. Pretty happy with my purchase as i did all my research beforehand. Only observation I have to share with potential buyers is that 83 inch model is dimmer compared to 65 inch model due to its sheer size, hence do keep in mind before making a purchase.
As i have set it up in the bedroom and dont have any direct light coming into the room during the day it works well. I am extremely satisfied with the default picture modes available ( Filmmaker / Cinema Home, etc). SD content is best avoided on a OLED as per my experience.
My primary media consumption is from OTT platforms, You Tube and occasionally a movie from Himedia player. I had to add a Sound bar (Samsung Q990B) as the TV speakers are really pathetic and you wont enjoy them for any content. I would highly recommend as the Sound quality is amazing and the price was also a steal (72.5K).
My recommendation would be to hold for a few years till prices come down for the 77/83/88/97 inch models. The 83 inch C3 wont have MLA technology hence it will be similar to a C2 hence no major upgrade. Bigger sizes may also be available in QD OLED which will add to the options available for a buyer.
I personally believe in buying current products available as per my requirement. Technology will always keep evolving hence there will never be a perfect product....period.
