I suspect it has to do with the ratio of liquid volume to gas (head) volume. When bottling each bottle has a certain amount of headspace, while when kegging the amount of headspace relative to the liquid vloume is much smaller since there is only one vessel. Now, I am not talking about the speed of carbonation, just the final result (the equilibrium): ...
You might just need more time. I usually let mine go for 7-10 days total before. 5 days seems a little short to me even with your 30PSI upfront charge.
The carbonation process shouldn't matter with respect to your altitude. Inside your keg is a closed system. So the same rules of temperature and pressure applied will get you the same volumes of CO2. The rate at which the beer 'de-carbs' in the glass IS effected by your altitude however. So if you find that the beer is getting too flat to quickly, well ...
