(Caveat: I'm a complete beginner when it comes to color management)
It's a well known issue by now that things are displayed incorrectly in Fusion when using DaVinci Wide Gamut and RCM. I managed to find a workaround by disabling the view LUT and applying a Color Space Transform node right before the output that I disable when I'm done working in Fusion:
If I'm not mistaken, in RCM+DWG, things put into Fusion will automatically be converted to DaVinci Wide Gamut + Linear Gamma and this will convert the Linear Gamma to sRGB which can be displayed by an sRGB monitor without further adjustments. It's important to use custom Max Input to match whatever the max level is. By default, this seems to be 10 000 nits when just using the DWG preset.
When doing this, Fusion displays pretty much what I see in the other pages and it also makes total sense from a color management perspective. What doesn't make sense is why the Managed view LUT gets it completely wrong. It seems like it's not doing any tone mapping when going from DWG/Linear to sRGB/sRGB which makes it look completely off.
However, I notice now that it's not quite right even with this workaround... the contrast is a bit off and I don't know why, maybe the tone mapping of Color Space Transform is different from the tone mapping done by the color module output.
