Question for NGFW, since they operate on the application layer, does this grant them the capabilities to view other layers such as layer 4, 3 and et cetera?

Question
The features you listed (malware inspection, content filtering, IDS/IPS) for UTM cannot be performed solely at Layer 4. They require advanced capabilities, primarily at Layer 7 (Application Layer) which can be seen/provided by NGFWs.
So does this mean the UTM definition that you provide here is incorrect?
I am confused.
Thanks for great quality education.
