The page says it should work on my phone but it doesn't. No difference between the SDR and HDR versions on my phone (S26 Ultra / Chrome).

It also depends on your screen brightness. In my case, if it’s set to maximum, there is no difference between SDR and HDR.

		That's what I'm finding as I researched it: Android's HDR brightness slider is low - The single most common "HDR does nothing" report on Android 15/16 devices. Samsung also has Super HDR/Extra brightness / Vision booster toggles under Display. Any of them at the conservative setting would have an effect.

		Came here to say this. It just cranks the brightness up for the pixels. But if you are already at 100% there is not much headroom so all the "before and after" for me were pretty hard to differentiate. There was some minor difference if I studied it closely but I'd probably not notice it during normal use it was so slight. If I went down to say 50% brightness then it was much more pronounced, but who lives their life with their eyes only half open like that?!

I was only able to test it on my iPhone. Let me see if the S26 needs a tweak (or confirm if it's not support)
