It is not simply burning

Maillard chemistry can occur before charring and produces a complex mixture of compounds.

Temperature and moisture matter

Surface drying and sufficient heat generally make browning more noticeable.

Food chemistry is complicated

Different ingredients produce different reaction pathways and flavour profiles.

It differs from caramelization

Caramelization primarily involves sugar chemistry without requiring amino compounds.
