Suspension, Wheels & Tires • SD front and HD rear brakes?

Hi, I'm changing the rear brakes on a family members '19 Flex SEL and there are vented rotors which I believe means it has the HD brakes. BUT when I look at the front brakes they are not vented in the hat like all of the HD rotors I see pics of. They are not the original owner so no idea if the fronts are original or not.

Could this car have SD front and HD rear?

If they are HD front does this just have some crappy aftermarket rotor? *I looked and didn't see an option for an HD front rotor that was not vented in the rear.

TIA, I appreciate any assistance.

Rear:


Front:
