Where, of all things, the real special feature of the Plena and the major differences to the Sigma you'll find in the amount of optical vignetting.
This may not bother everyone, but should still be neutrally weighted and addressed in a review of a lens like the Plena, whose main criterion is precisely the unique selling point in the area of optical vignetting and light fall off.
It could be because of all the compromises a lens must make, optical vignetting is the most easily addressed in post. Also to be considered is that vignetting is often added in post rather than diminished. So, the value of the small differences in vignetting between these two lenses is small in practice. I think few would pay the price premium for this. The other benefits of the Plena may provide more value to most.
The "Light Falloff" yes, but not the effect of the optical vignetting, which leads to the truncation of light circles towards the borders of the frame, aka cat's eyes/swirly bokeh.
That's where the Plena's unique selling point lies, the rendering of out-of-focus point-light sources with an unrivaled low amoiunt of optical vignetting and this was also the inspiration for its name.
I'm far from a pro at PP, so maybe I'm missing something, but it would be news to me that there are easy ways to reverse the negative effects of optical vignetting, resulting in a clearly visible cat's eyes/swirlybokeh in PP so easily.
