is this correct?

[Ana Laura]

hello..

I have 2 sentences:

a- we saw the young dancer rehearse for the opening night
b- we saw the young dancer rehearsing for the opening night

My answer would be:

a- it means I saw only the part of what was actually happening
b- I saw the whole performance.

Am I right?

Thank you.

Hello Ana Laura

I would look at it slightly differently. To my ears, the speaker in the first sentence is looking at the event as a whole; while the speaker in the second sentence is looking at the event as "something happening". But without more context, I wouldn't like to say which speaker had witnessed more of the performance!
