I bought a KOGAN ZU9010 4K LED SMARTERTV™ just when they came out. A few months ago the remote control got irreparably broken (don't ask) so I contacted Kogan to buy a replacement.
Unfortunately, Kogan doesn't have a replacement remote control for this model, nor can they give me details so I can program an IR blaster. I've tried dozens of different IR blaster configurations, all to no avail.
TL;DR - if you buy a Kogan branded TV you may end up with an effectively bricked device if the remote control is lost or broken.
