Apologies for continuing this off-topic discussion - but I figure this is now the relevant place to do so …
On the basis that one is shooting in RAW, may I ask why you suggest this?
My understanding is that a RAW file is not specific to either sRGB or AdobeRGB (instead, it contains data “in the native colour space of the camera”). So, when a RAW file is read by PL it converts the RGB values from this native colour space of the camera into AdobeRGB (which is PL’s working colour space).
Note: I’m quoting Wolf, from DxO, here.
My conclusion from this is that it doesn’t matter which colour-space setting we apply in-camera, provided we’re shooting RAW. Have I misunderstood something ?
