There was little to write home about in the Championship clash on Sunday as the two failed to light up the King Power Stadium - with City striker Chris Wood's late shot against the post the stand-out moment.
That was the only incident to cause McDermott concern, though, as he watched his side extend their unbeaten start to the season to three games.
"They hit the post, but we started well and I thought we might have nicked a goal," the former Reading manager said.
"We had a good chance through a Matt Smith header but there was not much in the game. We nullified each other and it was very tight.
"But this is not an easy place to come and get a result from. Home or away, you try and win the game and it is what it is. We've got four points and it's nice to get off to a start. We have a couple of good results."
With this result and last week's win against Brighton to their name, Leeds have taken four points from two of last season's play-off semi-finalists.
This was a marked improvement on the road for McDermott's men too, for last season they were susceptible to conceding late goals in games as tight as this one.
"They had the one chance against the post but other than that, they threw a lot of balls into the box and we dealt with it very well," McDermott added.
"I never look at it (being home or away). I look how each game is unfolding and we could have nicked that but we will take a clean sheet."
McDermott's chipper mood was matched by opposite number Nigel Pearson, whose men are also waiting to taste defeat this season and boast an identical record to that of Leeds - two victories and a draw.
He watched his side struggle in the first half but they were comfortably the more attacking side after the break, with Wood's effort their main return.
"I think it was always going to be tight," Pearson said.
"Leeds came with a decent game plan and tried to limit the number of chances we had. We had the best clear-cut chances but we were unable to take one.
"I thought it was an interesting game with two decent sides who cancelled each other out. It was a decent game and I felt comfortable throughout.
"You credit Leeds for how they went about the game and that was how games are in the Championship - very tight and there for the taking."
