Depends which part of the engine the oil is in, quality of oil before it begins to break down etc.
For instance oil at the main bearings is likely to be much hotter than in the block next to a coolant jacket and under higher pressure too.
From experience the coolant will always boil and cause an alert before the oil degrades even with its raised boiling point due to being pressurised and containing antifreeze.
If the cooling system isn't doing the job it's supposed to be doing and exchanging heat away from the engine then yes, your oil will be heading towards hot, this is why oil coolers are fitted to most engines.
