To be clear, you’re not going to find many displays that can reach 4,000 nits yet. A lot of HDR content actually is mastered for 1,000 nits and that’s considered kind of the target for the mid-high range OLEDs right now. My pretty much top of the line QD-OLED Samsung S95C maxes out at something like 1350 nits. A 1000 nit capable Steam Deck OLED has plenty of range in luminance for HDR to be effective there. And I’m sure it’s got pretty good color reproduction which is the other big aspect of HDR.
One thing we haven’t talked about is the possibility that the Steam Deck is enhancing SDR content with dynamic tone mapping to such a degree that it’s difficult to tell the difference when you actually enable true HDR. I’d really have to see this with my own eyes to be able to say with more certainty what’s going on.
By that logic, there’s nothing guaranteeing iMessage on iPhones is secure or private either because it’s closed source. If you don’t want to trust Beeper mini, you’ll be free to run their iMessage bridge on your own Matrix stack when they open source it at some point, which they’re promising to do (and you still won’t know that Apple isn’t scraping your messages on the iOS side). When I decide to trust a company, it’s because I look at what they’re transparently communicating to their end users. Every indication is that they are trying to get out of the middle of handling encrypted messages. Their first move to make this happen was allowing people to self host their own Beeper bridges (which you can still do with Beeper Cloud if you prefer and you will know that your messages are always encrypted within the Beeper infrastructure). They aren’t going to release the source for their client ever because that’s the only way they make any money.
