Not at all. Even if someone does have a platinum that is relatively easy to get, why does it matter? Just count that one out then if you're looking at someone's trophy list for platinum's.
I only have 4 platinums and one of them is from Terminator Salvation. To get that platinum you just have to play through the game once on hard difficulty. Even though that is an easy as fuck platinum to get it doesn't change the fact that I got platinum trophies in other games.
The other 3 games I have a platinum in are Uncharted 2, Red: Faction Armageddon, and God of War 3 Remastered. ( I got the GOW3R platinum like a month ago too).
