BI'm just trying to understand the use case here for the TV when you compare just the brightness for both the units. I'm not saying OLED is the best overall tech for the TVs. However, I have had better movie watching experience with OLED when compared to mini LED overall, may just be perception!. The same folks who say 'OLED is the best tech for TV' do emphasize the use case and dark ambience while watching is what I have heard/read.
Fundamentally, mini LED is designed to shine brighter and the current gen of OLED are still restricted with ABL and other tech to ensure they don't go that bright to prolong OLED's life. I see with heatsink in G2 and even going beyond, the QD-OLED tech, they are almost gone. These units are touching max of 1000+ cd/m2 which is just perfect for movie watching, most HDR movies are mastered within this brightness range only. I'm not sure how much benefit a higher brightness would bring to the experience, unless the ambience light is inappropriate for the purpose.
I did notice the black crush and some details missing when I saw the comparison you talked about. I'm watching it in the bright ambient light, even with the dark room there would be some details missing so yes there seems to be the black crush issues with OLED as rting review mentioned.
However, I think that's not the only parameter on which their ratings are based.
In this context, the question would be, what would hurt the movie watching experience more? blooming around bright objects and too much of bright pixels spreading the light on adjacent ones/area OR black crush that hides some details. Burn-in issues are almost unheard of these days. I guess purely depends on the use case. So, looks like there is a good balance and purpose for these units.
Another thing that I'm puzzled is the overall rating when I see comparison by rtings. Why do they rate OLED a couple of points above the best mini LED for local dimming? Even with such a big difference in brightness numbers, why would they rate movie watching (HDR or otherwise) higher for OLED? This difference only increases further when you bring in G2 and QD-OLED in the picture. Are they missing something?
