I understand that the \hyphenation command is case-sensitive when it comes to the words placed in its argument. For example, the command \hyphenation{SU-MA-TRA} will affect the words "SUMATRA", "Sumatra", and "sumatra", while the command \hyphenation{Su-ma-tra} will only affect the words "Sumatra" and "sumatra". In general, which case-variants of a given word are affected by a given case-variant of a word provided in the argument to the \hyphenation command?

Compile the following with tex:



(but any engine will do). The console will show

Underfull \hbox (badness 10000) in paragraph at lines 3--3
[] \tenrm kop-fw-poj-a-ww-hjr-eltr

Underfull \hbox (badness 10000) in paragraph at lines 4--4

Underfull \hbox (badness 10000) in paragraph at lines 5--5
[] \tenrm Kop-fw-poj-a-ww-hjr-eltr

proving that the capitalization of the words in the document is irrelevant.

Now try



and the console output will be exactly the same.

Unless you play nasty things with \lccode, there is no difference whether you capitalize the words in the \hyphenation list.
