@John1:
As per my first answer I state maybe an PL. Due to the fact no coin has such attribution except "brilliant uncirculated" MSxx, first coin on this post I think meet this criteria.
Now , what links you give me, only one show an TV photo here posted:

The same coin on the e-bay it is from GC which now improve the quality of theirs photo. Phill the inventor of the TV photo for PCGS, now work with Ian at GC.
We have 3 big beasts on coins photo: TV PCGS, PhotoVision NCG and GC. All has some advantages and disadvantages.
On the proof vs brilliant uncirculated the main point to brink an decision it is the texture of the low flat of the coins and the finish of the high design.
By photo is hard to decide. Till now only TV photos show as the grader see the coin, and this in part is due to the one axial light. The others use 2 angle lights and different filters.
