I was able to watch the Apple presentation today regarding their product announcements. There will be updates to both the iPad and iPad Mini but what got my attention is the iPhone 13 will have a 800 nits of standard viewing. I already have the Tripltek Pro, so I'm set with it's 1200 nits 
Here is some information from Apple Insider:
They are OLED, giving them a contrast ratio of 2,000,000:1, as well as HDR support. The panels also offer Wide Color Display (P3) support and True Tone, as well as Haptic Touch.
The iPhone 12 mini and iPhone 12 have a max typical brightness of 625 nits, rising to a peak brightness of 1,200 nits for HDR content.
On the resolution side, the iPhone 12 is higher than the iPhone 12 mini at 2,532 by 1,170 pixels versus 2,340 by 1,080. The size difference does mean the iPhone 12 mini has a higher pixel density of 476ppi vs 460, despite the resolution drop.
The iPhone 13 mini and iPhone 13 feature the same overall display specifications with minor upgrades in terms of brightness. The iPhone 13 mini and iPhone 13 both provide up to 800 nits of typical brightness, or up to 1,200 nits of max brightness when viewing HDR content.
As far as the actual physical screen, Apple says it has redesigned the TrueDepth sensor suite to allow for a slightly smaller notch.
