No, HDR can’t make your monitor brighter than it is. But it can take full advantage of the brightness and contrast of modern displays in a way SDR cannot. In almost every case HDR looks better than SDR but brighter and/or more contrasty displays take the most advantage.
In a more technical sense, SDR content is mastered with a peak brightness of 100 nits in mind. HDR is mastered for a peak brightness of 1000 nits, sometimes 2000 nits and the resulting improved contrast.
If you don’t watch movies in HDR on a modern TV, you’re not taking full advantage of its capabilities.
