There are sites like this one, https://jollyturns.com/resort/canada/mont-tremblant/maps/skirun/dynamite and you can take the arcsine of the drop over the length, but it's averaged over the whole length and who knows how accurate.
You can believe the hype.
You can take other people's word for it, but you don't know what their experience and standard for comparison is.
You really have to ski it to know what it's like.
For example I have skied all over Tremblant. If you have skied steep terrain out west, you will not be impressed by anything there, except maybe by how icy it is, if you didn't grow up skiing ice.
As to double black diamonds and grade inflation, the grading system is relative to other runs on the mountain, that includes the double black designation.
