Is the video acquired through AVCaptureSession gamma corrected?

I wrote the code to get the video through AVCaptureSession.

the code looks like the following.

func captureOutput(_ output: AVCaptureOutput, didOutput sampleBuffer: CMSampleBuffer, from connection: AVCaptureConnection) {
    let pixelBuffer: CVPixelBuffer = CMSampleBufferGetImageBuffer(sampleBuffer)!
    CVPixelBufferLockBaseAddress(pixelBuffer, CVPixelBufferLockFlags(rawValue: 0))
    guard let baseRawAddress = CVPixelBufferGetBaseAddress(pixelBuffer) else {
        return
    }
    
    // Convert the base address to a safe pointer of the appropriate type
    let opaquePtr = OpaquePointer(baseRawAddress)
    let baseAddress = UnsafeMutablePointer<UInt8>(opaquePtr)
    let byteBuffer = UnsafeMutablePointer<UInt8>(baseAddress)
    
    CVPixelBufferUnlockBaseAddress(pixelBuffer, CVPixelBufferLockFlags(rawValue: 0))
}

Is gamma correction already applied to the color information of the pixels(byteBuffer in above swift code) retrieved here?

If so, is it possible to retrieve the gamma value?
