It looks like metadata is ignored and instead we should set the grpc.primary_user_agent channel option instead. User-agent will change from: grpc-python/1.71.0 grpc-c/46.0.0 (linux; chttp2) to: OTel-OTLP-Exporter-Python/1.34.1 grpc-python/1.71.0 grpc-c/46.0.0 (linux; chttp2)

to:
OTel-OTLP-Exporter-Python/1.34.1 grpc-python/1.71.0 grpc-c/46.0.0 (linux; chttp2)
