I don't really see anything in that video that is necessarily biased, except them liking the display. And they do show what a picture of the mini-LED taken on a iPhone vs a real camera looks like. You think they are faking the review just to make it look better. He even points out when blooming happened.
Blooming only seems to happen at 100% brightness. This review does the same thing at 100% brightness. Yes, it happens but who actually watches at 100% brightness. It seems that every display tech has its pros and cons. Micro-LED might also have some faults when it actually states being mass produced.
