Range reach API

I am using Reachable Range API, I am testing the difference between HERE and TomTom API.

Why is TomTom API return sharp ages polygon whereas HERE gives very nice polygons? see below.
Am I missing some setting?

Results from TomTom API:

Results from HERE API:

Can I get the results from TomTom to be as smooth as from HERE?

In my opinion TomTom APIs usually offers very raw data, but that gives you a lot of possibilities to transform that data.
In this example - TomTom gives only points that are located on the road, while Here is adding some additional points which just make look better. I think that you can achieve similar result with e.g. turfjs
