For me, I can barely detect any palatalisation down here. For instance,
I can remember having a discussion with with a friend of mine in first
year about the how "spideog" is pronounced. She, and she's a gaeilgeoir
BTW, pronounced it as, as it sounded to me, [spId'o:g], whereas I
pronounced it as [SpIdZj'og]. I couldn't hear any changes between her
slender and broad consonants.

Or maybe Irish is losing them under influence from English...
