I think you’ve done a wonderful job with the flower. Honestly this was over a year ago, so I can’t remember exactly what it looks like, but it was definitely quite orange.
The different flavours of the auto curve in RT are very different colorwise esp wrt saturation…Standard and film seem to be more saturated but in any case you would have to try them all in this sort of comparison…
the checkerboard pixels are the marked out-of-gamut pixels, mainly in the noise in that dark spot.
fwiw the red seems to stay within rec2020 at full saturation.
input colour is from a spectral sensitivity function lut, saturation reduction preserves hue (it is orange).
flowers are pretty tricky - had one of these in my garden so tried to keep it natural looking and it is quite a deep orange. kept the background more - well, in the background- and to keep some of the vividness of the flower by contrast
