Traditionally this holds true, especially if you did well and not merely OK on step 1. That said, step 2 does help and you have to weigh when to take it on the basis of a number of factors such as 1.) do you have enough dedicated study time to prepare well, based on how you've done on shelf exams so far and 2.) is the score likely to go up or down with respect to the step 1 score, and if so, by how much. If you got a step 1 of 260 and you're getting self-assessment projections of step 2 of 230, maybe hold off until a bit later in the year; if on the other hand you're doing better on self-assessments and practice exams, especially significantly so, then it might be a strength to have a markedly improved step 2 ck in your application.
That said, once programs have crossed the threshhold to interview you without step 2 ck, I think they do not find that the score matters all that much to them. I've noticed that in my case, where despite a 20+ increase in my step 2 ck vs. step 1, and a recent email notifying programs I interviewed at that the USMLE transcript is updated, very few programs have re-downloaded the updated transcript, which tells me that it's not a big deal for them at this stage of the game.
