The short answer is yes. The long answer is more nuanced. It depends on the yeast and your ingredients. Also, unless you've tasted a lot of beers at various stages, it may be hard to discern how the final product will taste. You can have a beer that tastes ok when bottling that turns out to be a good beer and you could have a great beer that is delicious when bottling. Some flavors will mellow over time, and tasting temperature can be a big factor.
With that said, fermentation temperature control is important in beer quality.
