It is likely using a symbolic icon in the system tray, which is expected behavior. If symbolic icon is present, the system tray will always prefer that over the colored one. Some applications let you change the color of the system tray icon.

Your explanation doesn't account for the fact that the tray icon is colored in Plasma 6.2.x. If the tray icon will always prefer the symbolic one over the colored one, the tray icon should be colorless in Plasma 6.2.x too.

The added code to prefer symbolic icons was introduced in Plasma 6.3, which is why it changed for you after you upgraded to Plasma 6.3. As such, I'm afraid this is considered intentional.
