Can you give more info about this two XPE2 leds? (image inside)

They are both XPE2 red Cree leds, first one I ordered form BLF member, I think it was somewhere around 2016!
I asked for best red leds he had and I believe he said they were P4 bin, not sure.
Recently I ordered some from Intl-Outdoor, I requested also P4 bin, according to this table P4 should be highest bin in offer:


But they are phisically different as you can see from this image (older one has more “separations”):

Maybe someone ordered this from mouser or element14 and has this long order code and is willing to compare his leds with this images?
Trying to identify what I actually received.

Thanks

Emitters are always improoving m8, in your case you have 2 different core xpe2 revisions , the first isnt P4 definately, the second is probably a P4 binned one.

Sadly, youll never know what you actualy got case even Mouser( i am sure about this) dont knwo what exacly they are selling
