Yes; you should expect that!
One should also be able to explain complex ideas in language simple enough that anyone can get it - so with the crayons out, here is a little illustration of the only quality that matters in the clock output, down to 10s-of-pS deviation as I wrote above: this is what 'jitter' is in a clock signal:
Any o'scope internal timebase performance is c. at least 10^4 x worse than the clock in this regard, so it cannot be seen on a scope directly. The crests of the clock signal, high and low, are way above/ below the slicing level where the dac converts the signal (which are usu c 0.6v from each of high and low voltages. Which is what the shape at the extremes, really doesn't matter.
- Now go read the earlier post above, again, with this illustration in mind, until you get it.
