I thought it was well known that MVNOs are on lower QoS/prioritisation than the carrier's own main brand(s)? A mate works for Optus and had for a while a bunch of different iPhones of the same generation for testing. Each had the same OS version/etc. One on Optus Business, one on Retail Postpaid and one on a reseller (iirc Virgin). Speed tests side by side were pretty interesting. You could quite clearly see the business service was getting prioritisation over all the others. Retail was generally better than the Reseller by quite a margin. Some locations (like shopping centres) would restrict the reseller from working at all, and retail would be clamped down on bandwidth.

Does it actually impact speed or just QoS? I'm on an Optus reseller network and basically can't see any problems - 1080p streaming and Duo video calls work without and with low latency. Even if I'm prioritised lower than business, I wouldn't be able to tell the difference.

  It definitely affected throughput. i.e take the phones out, and run all the speed tests at once - the business plan was guaranteed to run faster. It wasn't like it was an issue with one particular phone just being better - you could swap the sim cards between phones and no matter what device the business sim was in, it got the best throughput. How they actually implemented it I don't know, all we could go on was based on some testing from an end-user perspective.

    I should've been more explicit. I meant, does it impact speed in a meaningful way? Once we can send+receive real time high quality video stream on a retail plan... Does it matter that is slower than the business one?

      It'll depend on your use case, and your location and other conditions. It wasn't done as a "isn't that interesting" thing, it was because of some specific problem with a client that was reporting poor performance.
