The former Toffees forward scored Norwich's opening goal in their eventual 2-0 win in the third round of the EFL Cup at Goodison Park, with home supporters applauding their former player.
Of the positive treatment Naismith was the subject of, Neil said: "I think it speaks volumes of Steven as a lad.
"It doesn't happen for every player when they go back, a lot of them get booed and get stick. They obviously hold him in high regard.
"He's a really good lad, he works extremely hard, he's honest and I think certainly most fans, if there's an honesty about a player and you know that he's going to give everything he's got, then they appreciate that.
"I thought it was a great touch for him that he got that reception."
