My opionion is that you should go to the vet and get a professional opionion. It is hard for us to say by looking at the pics and better to be safe than sorry. If there is an issue with the ears and you catch it early enough you will have an easier time to correct it than if you wait. Anytime something is a color that it should not be indicates a warning to check it out. Please let us know what the vet says.
