Couldn’t this be due to the display calibration?
Sure, I’ll give it a try when I get a chance. I’m definitely interested in seeing if I can get other shaders to look better using RetroArch’s HDR implementation.
Is this the same Mini LED you got recently?
Anyway, I tried your settings. What worked for me was Peak and Paperwhite Luminance at 630. 6.3 was the lowest I could set the contrast and still barely make out the second to last bar in the grey ramp test and also differentiate between the 2 brightest bars.
While 5.3 might work in a dark room, I kinda settled on 5.7 for now after testing in games. So it was in fact actually pretty simple to get CRT-Guest-Advanced looking great in HDR. All that was needed was a little impetus.
This is just a starting point, imagine what can be done now with all the tools that we have at our disposal?
Concerning this, I noticed that with Expand Colour Gamut On, everything looked slightly cooler and more saturated, while with it off, things looked slightly warmer with less saturation. Whites looked more neutral with it on to me. I didn’t notice any tinting that would cause me to loose any sleep over.
In order to further raise awareness of what we are trying to accomplish, please allow me to share my first configuration override.
