Is that actually true? What's the sampling rate and subsequent Nyquist frequency? It's my impression that the sampling rate given by ice core samples is surprisingly high (something in the neighborhood of year-by-year.)

Ice cores only cover hundreds of thousands of years into the past (I think the oldest is about 800,000 years). I'm talking about times millions of years ago.
