I mean yeah I have the same issue too (escept I use around 20-25% brightness on my OLED). But HDR is about more than just brightness. For me it’s worth it for the extra colors—especially teal—which SDR displays struggle the most at reproducing accurately.
Interesting observation on the colours! To be honest I never got past the brightness when I turned it on. I couldn’t get past a couple of minutes before feeling like my eyes were being burned by the hellfires of Satan’s asshole.
Granted it might be the IPS panel (aw3821dw), so I would have to upgrade to an ultra wide 220ppi OLED to test out this HDR that everyone’s raving about when it becomes available … for science. RIP my wallet.
