What is the difference between these hat badges

[HistUS8106]

These are different hat badges. Are they USN hat badges from WWII? What is the difference between these two hat badges?

One is USN and one is USMC. Neither looks WW2.

If you could show the whole picture it might be easier to put a date on them. 
 

The insignias are so small on my screen that when I blow them up they blur too much to discern any detail.

Is the second photo AI or something? The first one is definitely Bob Feller in 1945
The second is supposed to Bob Feller in 1945

More AI created nonsense?

What’s going on?

 

The US Marine is in the wrong uniform.

The navy hat badge has a slanted N which went out in 1944.

AI was used to colorize the photo  and it messed up the insignia.    AI does not do well with insignia.  It’s the easiest way to id an AI created/enhanced photo.

I'd ask for a source and a scan of one page from it but I've learned that's a big ask.

 

I can only google this stuff.

USMC caps, do not have the black band around them

Looks like the chain around the bottom of the navy emblem is incorporated into the Marine Corps emblem. I didn't know the AI color programs also did "corrections" like this.
