They’re not of much use if I’m still going to get the same “floating lights” in most of my night photos and videos
How do you know that you will? Don't you currently shoot with a 13PM, which easily flares? Which was taken care of with the 14PM.
Why not give a 16PM a try and see if it still happens? I know it doesn't on my 15PM (unlike my 12PM which easily flared with off-axis Sun light). If it does, simply return it during the return window.
