Adding a bit more to my earlier replies - the kind of imager (like me) who uses Bayer Drizzle to obtain greater resolution from an already pin-sharp image is the definitely the kind of user who will notice green or pink stars. On the other hand an imager who takes Milky Way landscape pictures and only displays them at web size will (probably) never notice. Most imagers fall somewhere between these two extremes.
There is an interesting pattern that has emerged every time Sony releases a new mirrorless camera. Someone takes an astro-landscape image and makes a name for themselves by boldly declaring that this time Sony has completely fixed the issue.
e.g. the Sony A7R3: Sony a7R III: The Star Eater is No More (Petapixel)
followed one week later by: The Sony a7R III Eats Stars: New Report (Petapixel)
The problem is usually that the original image shows a small amount of star trailing, imperceptible for a web-size image but sufficient to protect the stars from spatial filter damage.
