Is the word espelho the same in Brazilian and European Portuguese?

Yes

The word "espelho" is identical in both Brazilian and Continental Portuguese in terms of meaning, spelling, grammar, and usage. The only differences lie in pronunciation.

In Brazilian Portuguese, the vowels tend to be more "open" and clearly articulated; the "e" in espelho is usually pronounced distinctly. In Continental Portuguese, unstressed vowels are often "closed" or even reduced to the point of being nearly silent, meaning the "e" might be much shorter or softer. Additionally, the rhythm of the word follows the more syllabic nature of Brazilian speech compared to the stress-timed nature of European Portuguese.
