I don't know if it makes any difference to your findings, but I would point out the test hardware is neither representative of most devices supported by OpenWRT, nor those on the amazon best-seller list that I see looking from Germany:
Five of the top-10 devices on that list are arm64 (little-endian, hardware TLB walker, typically 512MB of RAM), the others are mips32 (typically only 128MB, mostly single-core) and only the oldest one (Archer C7) of them is big-endian. I would not expect endianness to make any difference, but the 16x smaller memory of typical mips devices (ath79, mt76) might.
