The numbers youve posted are the panel types, not the type of the TV. Seems like Samsung used diefferent Types in this set.
The number is divided in severel sections:

Inch
Vendor (A:AMLCD, D:CMO, L:AUO, I:CPT)
Panel frequency (6:50/60Hz, 1:100/120Hz, 2:200/240Hz)
Panel (A:AG, T:TN U:UC)
Resolution (F:FHD, H:HD, U:UD)
Panel 1st/2nd (1st:0, 2nd:1?)
BLU (C:CCFL, L:LED, E:Edge LED)

Since your TV has a 100Hz panel it cant have the 55A2UF0E, since that is 200Hz.

As far as I researched it may be the 55P1UF0E. If not then I would try the 55A1UF0E next.

What consequences does it have? Have you noticed any troubles? If not, it is ok, nothing bad happened

I change accidentaly on my sasmung 55es7000, and i don't know that to select of this option?

Panel 1st/2nd (1st:0, 2nd:1?)
