Yeah, it's designed to generate max power without hurting the engines. The titanium turbine blades start to abrade above 820-850 C, so the idea is to keep ITT no higher than 800 or so. This is not a catastrophic failure issue, but just a gradual wear issue...makes the engines last longer.
At TO/GA or APR power, you're not overstressing the engine, but you are wearing out the turbine blades.
Remember, the CF34 core is a de-rated military engine (A-10 and S-3).
