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

Yes

The word "incríveis" is identical in spelling, meaning, and grammar in both Brazilian and Continental Portuguese. The only difference lies in pronunciation.

In Brazilian Portuguese, the vowels are generally more "open" and the syllables are pronounced more clearly. In Continental Portuguese, there is a strong tendency toward vowel reduction; the unstressed "e" in "incríveis" may be pronounced very subtly, almost like a swallowed or silent sound, making the word sound more "closed" or clipped to a Brazilian ear.
