General query regarding Lenovo K8 Plus display screen.

As we know Lenovo has provided gorilla glass 3 protection in K8 plus. Also the display is 2.5D curved. I want to know that do we need to use screen protectors for this phone?? Because i have wasted more than  Rs. 500 for buying screen protectors and tempered glasses but any protector is not able to cover edge to edge and tempered glass comes out from the edges. I know that due to curved display the protectors are coming out from edges. The solution to this is to use short tempered glass which covers only the flat surface. This looks very bad. Should we use protectors or the gorilla glass will naturally protect from scratches. Is is okay to not use protectors?? Please suggest.

Thanks.
