Because it's digital, and there is processing of some sort involved, how it gets processed could affect how it comes out.
Generally image-sensors don't actually do a photo-site to pixel 1:1 mapping. There are multiple "colours" of photo-sites, and an interpolation algorithm involved in determining what "colour" any given pixel should be.
Most sensors have an arrangement along these lines:
GREEN RED
BLUE GREEN
and the colour of each pixel in the "raw" image is determined by averaging the input from the neighboring photo sites of the other colours.
Adjusting that algorithm could make a big difference in how something like a lens flare, where there is the potential for massive differences in the intensity of light hitting adjacent photo-sites is interpreted.
The differences between say, an algorithm that "chooses" to exaggerate the differences to make the image look "sharper", vs. an algorithm that is designed to "smooth" the transitions, vs. an algorithm that changes it's behaviour depending on how bright pixels are vs. their surrounding ones, or what colour the light has averaged out to etc.., and whether the scales used in the algorithm are linear or algorithmic etc.. could all, at least in theory, make a HUGE difference in the appearance of bokeh, every bit as much as the differences between various types of film will. Kodak Portra will have much smoother bokeh than Kodak T-Max, due to the nature of the underlying emulsion, and the chemicals used, chemistry temperature, chemical dilution, and developing timecan results in significantly different looks with all other things being identical.

Bokeh is a property of the lens, not the body.
Let's not 'put mayo' on the good news of this upgrade.
