Linear file generated from DPP4, useful in darktable?

In Canon Photo Professional 4, there is linear feature “when you adjust images using image editing software that has advanced editing functions.”

If I get a new Canon camera without raw support in darktable, would this feature be of any use for me in darktable? I tried and this was the closest I could get, but feeling the green background look a little bit off.
What do you think? Something to forget or perhaps useful in some rare cases?

Would the box you showed say linear not standard…looks like you are showing an auto levels and S curve but talking about linear??
