Hard to say, since we don't know what such perfect play would look like. But I expect it would look quite boring, yes.

It's important to state, though, that calling an engine's play "romantic" is not a value judgement. Stockfish and other engines play in a way that give a clear concrete advantage after X moves, whereas AlphaZero relatively prefers move that are "creative" or "beautiful" in the sense that there's less of a clear definite benefit, but instead some sort of slight positional advantage or more attacking chances or something similar. It's harder to prove that it was a good move, but it just "feels" good. In that sense humans enjoy it either since it's surprising, or maybe closer to how we're able to think.

As an example, there is one game I saw analyzed where AlphaZero gradually gives up more and more material with little clear compensation, but gradually its position gets better and better, until Stockfish is completely out of good moves. It then turns the corner, snatches up more material than it gave up, and converts into a winning end-game. Such imbalanced style of play is much more interesting to watch than previous computer slogs of slowly jockying for slight advantages until one side can grab a pawn without giving up much and build into a win from there.

There is no unlimited computing power anywhere, though. Not even in Google's quarters. The style difference is so profound that it is difficult to impute computing power only, because we know what kind of improvement reasonable computing power gives : it makes the engine stronger but does not quite change its style.
