So I know the first white square is max HDR brightness. Is the second slide with town and colors supposed to be max SDR nits? For example my LG 27GS95QE is 600 nits HDR (1000+ with MLA) and 276 nits SDR. I set the second to 276? It goes to 600 but i feel like HDR content is blown out with that.
Or is this trying to match brightness of SDR? I found a value of 450 does this roughly and looks good..
