If we compare sales to last gen version of GTA5, they aren't super different. GTA5 was more popular in Europe on last gen consoles despite the fact the hd market was much bigger in the USA.
The difference is a bit bigger now probably because the ps4 has a much bigger marketshare percentage in Europe than the ps3 did so the ps4 GTA5 bundle had a bigger effect in Europe.
