I know how bad the support for HDR is on computers (particularly Windows and cheap monitors), so I avoid consuming HDR content on them.
But I just purchased a new iPhone 17 Pro, and I was very surprised at how these HDR videos on social media still look like shit on apps like Instagram.
And even worse, the HDR video I shoot with my iPhone looks like shit even when playing it back on the same phone! After a few trials I had to just turn it off in the Camera app.
I have zero issues and only an exceptional image on W11 with a PG32UQX.
