I gotta be in some extreme minority group that loves the screen on my 16"MBP and really don't care if the blacks are deeper?
I shoot video and pictures with a Sony a7iii. I edit those from the MBP to a Viewsonic color calibrated 32" monitor so a laptop with a "better" screen is nice, but totally unnecessary in my workflow.
Sure, some people will be ecstatic, but then once the damn things are released to the public, there will be a plethora of posts here bitching and moaning about some aspect of these new displays.
Never fails.
