I think you're right in that there have not been any major breakthroughs as of yet, companies are offering blockchain services (IBM) and even exploring the potential themselves but I've not yet come across any stories highlighting the adoption and the benefits. It could be that it is too soon for that, even if blockchain technology was adopted it would take some time to be able to see results and draw comparisons to previous methods/systems.
Well there are benefits and perks for the companies adapting the technology but they are in the long run because of the fact that crypto has not yet spread around the world and as soon as the demand for this currency rises high, we will be well off with the adoption.
No doubt, some will be evident pretty soon. But crypto could end up being a different story. I'm yet to come across any project which really needs crypto for their underlying utility to come true. The only true use cases that have been proven so far can all be achieved by bitcoin and they mostly come in wealth preservation and transfer.
