Can confirm. We hit this exact issue running tirreno www.tirreno.com (open-source fraud detection) on Windows ARM — libraries were auto-selecting AVX2 through emulation and batch scoring was measurably slower than just forcing SSE2. The 256-bit ops get split under the emulation layer and the overhead adds up fast in tight loops. Pinned SSE2 for those builds. Counterintuitive but throughput went up.
