No, it's not. You answered your own question here:

> while keeping pitches the same

All 192khz does is preserve higher frequencies. If you're keeping pitches the same, there's no advantage to using an extremely high sampling rate for your source material. The advantage comes if you're going to lower pitches.

(Note that some algorithms need higher sampling rates to avoid aliasing. That shouldn't be the case anymore, but if you're hearing a substantial increase in quality just going up to 192 khz, most likely one of your algorithms is faulty.)

(Note 2: I say "substantial increase" because some people can detect up to 27khz.)
