iPhone 11 Pro Photos with Greenish Dots and Squiggles in Low Light Conditions

Greetings! I purchased an iPhone 11 Pro on launch day and am having trouble with photos in low light conditions.

The problem:

Photos taken in low light conditions (indoors or outdoors) have greenish dots and squiggles on them. The greenish dots and squiggles are visible on the screen prior to taking the shot, and are also visible in the image once the picture is taken.

Examples:

I've attached three recent examples. The condition has been present since receiving the phone on launch day.

Steps Taken:

I contacted Apple Support, described the conditions, and provided examples of the issue. I was told by the Apple Support Advisor that what I'm experiencing is totally normal.

I am struggling with this determination because no iPhone I've ever had does this. In a side-by-side comparison under the exact same conditions using my work iPhone 7 and my wife's iPhone 8, the older phones do not produce this effect.

Additional Facts:

(1) There is no plastic film or cover over the lenses;

(2) The issue occurs regardless of whether Live photos is enabled; and

(3) The issue is still present even if the screen is pressed to focus the image.

Any help the Community might have would be sincerely appreciated! I'm reading the rave reviews of this camera online, looking at the images produced published in the media and by others with the device, and am left feeling that there is something wrong with my particular phone.

Thank you!
