Yes, we make a lot of aesthetic decisions on how we portray the data we capture and this is just another one, IMHO

Get a FSQ-106, Ray! Your Airy disk in red would be about 3 arc sec.
Or, move your gear to SRO
Our Ceravolo 300 at SRO should have an Airy disk a little over 1 arc sec and the seeing is often better than that.

I'm happy with white cores on bright stars. I just like to see some colour around the core. As David Malin tells us, stars are black body radiators and should have pastel colours, so they can be brighter than 1/3 max.
